And Findekáno refuses to leave - points out they can have the conversation without him anyway - and is still there when Maedhros shows up.
"Hi," Maedhros says to both of them. "So, first, I was persuaded by being handed free will, but you'll only be able to verify that you have that if there's some future-binding positive oath you know you swore before you were taken prisoner, is there?"
"Nope."
"Okay. You can also get married, Enemy can't fake that, you could be stubborn and conclude he also has Findekáno but at that point the war's lost and I'd expect him to stop playing excruciatingly subtle games and just torture you both for all eternity, and also I still don't think he'd do it, it means he can't force you to father any children for him -"
"How long were you there?" Maitimo says.
"Fifty years."
"I don't know how your world works but I can't marry Findekáno -"
"Can too, it's expectation-controlled! It didn't make much sense that the universe regarded marriage as metaphysically for straight people. Uh, since we're going to give you free will afterwards what you ought to do is select a person who is exceptionally unlikely to be in Enemy hands, maybe someone who stayed in Valinor, marry them, then get free will, but I'm guessing that'd be difficult -"
"Could you do it?"
"Yes. I could. I'd be faking, and I'd feel weird about the other person's capacity to consent considering how much I'd be faking, but I could."
"I'm not positive the Enemy couldn't fake the person, if not the marriage."
"So then marry the obvious candidate, get free will, conclude you're not hallucinating. I might come up with something else that'll do it but I haven't yet."
"I'll grant you that this is at least the most setup Thauron's given one of his pickup lines."
Maedhros nods. "Then, once you believe this isn't a hallucination, you can learn to teleport and it helps, a ton, with the feeling that as long as it could possibly happen again there is no such thing as a life worth living. We also might be able to become the kind of thing Cam is, and that means as far as we know we can't be killed but we also are indestructible and nothing can ever seriously hurt us again. I have been weighing it. And there's a way to die but it depends on Loki and it'll hurt her if you ask so please don't, as a personal favor? It's a big multiverse, you can find a different one."
"Can I."
"You already know why you won't, you don't need -"
Maitimo sighs. "When we've fixed the multiverse?"
"Yeah, of course. We -" he looks at Findekáno - "I love him, I love my family, I love my people, but I am not sticking around for them, not once we've fixed the multiverse. If we still want to die then we can."
"If?" Maitimo says. "You're not sure?"
"I - suspect I won't want to. Things are tolerable a lot more often. There was something recently that made them much worse, I'm still in a mood about it, but the trajectory is good. Doesn't mean it'll be the same for you, of course."
He nods.
"I wanted to compare people, see who all we've got alts of -"
"Of course."
And they set to that, eyes alight like two people who do, however reluctantly, dig a great deal of joy out of living.
