Haru wakes up from his nightmare eventually, only to discover that it's still going on.
"Mom!" he cries out, and the impulse to holler at the top of his lungs, to be that much surer that she'll wake up, is warring with - what, that he doesn't want to annoy her? Of course it's not ideal to annoy her but - it's not usually the end of the world, why is it the end of the world - it would be the end of the world if she did something like leave the house but she won't, she'll wake up and come get him, she's got to - "Mom!" he yells again, more urgently, and she's not at his side yet and he throws himself out of bed. His foot, caught in the sheets, doesn't follow the rest of him, and he winds up capsizing into his door, catching his elbow on the doorknob, and collapsing in a heap on the floor. "MOM!" he screams, his voice cracking. He's not sure he can get up. He's not exactly weaker than usual or wobblier than usual but there's a futility to it, a chilly heaviness in his bones and a starving ache in his skin, like... what is this like. It's not a familiar sensation. It's... like he needs a hug so badly he will die without one.
Finally, after a thousand years, Ren opens his door and flicks on the light. "You fell?" she asks, reaching down to him.
He grabs her arm, tightly, much too tightly, and nearly pulls her down with him instead of getting up. "That's not - yes, but after I -" He needs a hug so badly he will die; he gets on his feet and without ever letting go of her he wraps his arms around her. It... helps, a little, a very little, the way it helps to pour a glass of water when you're very thirsty even in the moment before you drink any of it. Any second now he will stop dying of - this -
"After you what, sweetheart?" says Ren, maneuvering him back toward his bed to sit down. "Where'd you hurt yourself -"
He wiggles his elbow as much as he can without unhugging. Ren tries to unhug, presumably to inspect the elbow, and he makes some kind of desperate choking noise and squeezes tighter and she stops trying to do that.
"If you're not going to let me look at it how can I -" says Ren.
"It'll bruise. It's nothing. It's fine. That's not the problem," says Haru.
"What is the problem?"
"I don't know," says Haru, "I'm - I don't know -"
"I think I'd better call an ambulance," says Ren.
She is trying to stand up. She's trying to stand up to leave the room, what did he do wrong, why is she trying to leave him, "Mom, don't go, no, no, stay here - or I'll come with you! That's fine too, I got my elbow, not my knee, I can walk -"
"If you say so, honey. Is it like - are you seeing things, or did you have a nightmare, or..." She's half-supporting him out of the room and down the hallway, like he's got a broken ankle, which means at least they have practice. "Do you think you're running a fever?"
"More like a nightmare than the other things?" says Haru, grasping ineffectually for the reins of his panicking miserable brain. "I think I - did have a nightmare - am I still having it?"
"No, you're awake now." She picks up her phone, when they get to her room; she dials 119.
How would she know if he's awake or not. If he isn't awake, then she's a dream figment, and he hasn't successfully reached help at all, and he's thrashing around in his bed dying of needing a hug and no one's going to hug him. That would explain why he is still dying despite this hug. It's not helping at all. He thought he'd poured himself a glass of water and actually it's just more glass all through and he can't drink it. This isn't the real Ren, the real Ren is sleeping peacefully in her bed and she doesn't know he needs her and he doesn't know how to scream in his sleep so that a real person can hear him.
(She tells them she wants an ambulance for her son. She gives the address and her name and his.)
Maybe he is awake and - being awake just doesn't matter - what would have to happen for this to be enough, for this to work? She'd have to be a real person, obviously, but it's not like he can tell, he's not telepathic and if he were that would be abhorrent anyway, to go around checking that people had thoughts and experiences directly. If she's never been a real person throughout his entire life how would he even know? That would explain why holding her isn't working - he still can't stop, the fact that it isn't working doesn't remotely suffice to let him stop, but it would explain it maybe possibly, if she has never been a real person and he needs to be with a real person.
("He's seventeen," says Ren.)
It's separately very upsetting that he must now confront the possibility that he has been raised from infancy by some kind of dream/robot/actor/hallucination but he can process that later, the acute problem is just that right this minute he needs a real person, any real person, it doesn't have to be Ren, he would gladly go talk to the vaguely fascist konbini clerk about baseball and the virtues of the Axis powers, if he could first get Imaginary Ren to accompany him on the walk around the corner. Which she won't, because she is on the phone with emergency dispatch.
"Sweetheart, they want to know if you think you might be having an esper awakening," says Ren.
An -
No. Those, those are - they're supposed to be medical problems. He should be... blind or something. Having a seizure or a migraine or a rash. Throwing up or getting hives or suffocating or fainting from anime-worthy nosebleeds. Dying decently of some decent ailment. One's mother turning out not to be real is not a fucking medical problem. "What?" he croaks.
Ren's listening to the phone again. If she can listen to things. Well, maybe she can, one might colloquially say that a microphone listens to things. "I'm very sure he already knows the parameters of awakenings, ma'am," Ren says, "he's actually always wanted powers, but I can put him on the phone if you want."
Haru takes the phone. Maybe the ambulance dispatcher is real. He fills his voice with the phoniest most desperate cheer and grabs for the most respectful keigo he can. "I am so sorry to have troubled you at this hour!" he chirrups. "What is it that I can answer for you?" (Ren looks more concerned than ever.)
"Suwan-san, I only wanted to go over the signs of esper awakening with you so as to better prepare you and your mother and the ambulance team. It would have come on over a period of less than sixty minutes -"
"Mm?" he says, trying to sound fascinated by the first paragraph of a Wikipedia article he's read five times.
"- and it would come with a frightening and overwhelming set of symptoms that should at least not get further worse over the course of the week. Awakenings are almost never life-threatening in themselves, but if you're feeling destructive urges or having suicidal thoughts, then -"
This voice isn't a person either, Haru realizes. They have staffed ambulance dispatch with robots, which is really very efficient of them, only he would sort of desperately prefer a person right now. "I need to talk to a person," he says. "A real person."
"Suwan-san, can you tell me how you are feeling right now?" says the voice on the phone.
"You know, that's a great question, and I would love to talk about it with a real human person who exists? Do you have one of those? Connect to agent. Representative."
"........I will tell the paramedics what you tell me, Suwan-san."
That's just going to have to be good enough. "I feel like - I need a hug, but I'm getting a hug, I - oh, I'm lonely, I guess, I'm not used to that, it doesn't usually come up -"
Ren hugs him tighter. He wants it and he leans into it and it doesn't help. "That sounds like it could be an esper backlash," she offers softly. "Like you always wanted -"
He stares at her, at his unreal mother who cannot possibly squeeze him tightly enough to make this go away, if backlash is what it is. "I -"
He wanted esper powers to save people, to be a big damn hero out slaying dungeons and bringing the kidnapped to their grateful loved ones, and he was intending on, if ever he did have a week of some respectable medical problem like narcolepsy or delusional parasitosis or alien hand syndrome or sudden onset cystic fibrosis, scheduling a few minutes now and then to contemplate the rescued and the freedom with which they would live out the rest of their lives thanks to his enduring his normal fucking medical condition for them in order to save them with whatever cool magic powers he got.
"You're gonna be okay," Ren says.
He'd been planning to be super insufferably smug about it, but, like, privately, because nobody would need to know exactly how he'd derive his job satisfaction. This sounds so weird right now it's hard to remember right. He was just supposed to not tell anyone? He was supposed to bother to save people, who were supposed to have existed, and then not even necessarily learn their names and tell them he was glad they'd get to go home safely? Also they were supposed to have experiences both before and after the part where he rescued them. Yes, he wanted esper powers, but absolutely everything about his vision for the prospect is completely ruined. And also he's fucking dying of it.
"I don't think so," he tells her.
And is that even a problem? What was he supposed to be so excited to live for? Was he supposed to play Civilization all the time? Read books? Why do the robots even write books? He knows he has historically liked doing things that did not rely on people being nearby/real/talkative but he can't imagine concentrating on a book now. He doesn't think he could pick his way through a tragedy one iamb at a time. Maybe he could watch a play. If it were live. And the actors were people. Which does not seem very likely, now, does it.
And he could still do this for the next fifty years, if it would matter, if it would make him a savior, a hero, the coolest and most admirable goddamn human sacrifice on the planet. He could do it.
If there were anyone to save. If there were anyone who might hypothetically admire him or at least be mistaken in not doing so. If there were anyone.
"One week," says Ren, "I'll call in sick to work if you need me, I'll call your father to come here too, one week and then you get to be an esper, sweetheart -"
"It's not worth it," breathes Haru, his eyes stinging, his fingers cramping up where they're clenched in the sleeve of Ren's pajamas.
They've both of them all but forgotten the phone, but at that Ren grabs it from his lap and presses it to her ear. "We really need that ambulance," she tells the dispatcher, "now, immediately, please."
