She gets left alone a lot, though. Cindy is out doing things all the time. He doesn't have as much time to take her to the flying place. (Once, when he is out and she can't even ask, she hops out over the patio balcony onto the neighboring roof, and checks to see if there is anybody around, and flies a little bit, low and owl-quiet. She doesn't think anybody sees.) She builds elaborate structures. She solicits another box of pieces.
He leaves the news on, a lot. Pen mostly ignores it. She knows English, technically, but the pentagon didn't tell her the concepts her upbringing has left her missing.
"...of more than—oh my God."
The Joker bolts out of the kitchen just in time to catch the replay of the collapsing football field. He watches the screen intently, scrambling onto the closest couch for a better view, and the voiceover notes shakily that this is now coming in live as the camera pans over the flaming ruin that used to be part of the stands. Specifically, he is informed, the part of the stands containing the mayor of Gotham.
She frowns at the television.
He has a sense of theatre, at least, when he brings out that scientist type and has him identify the big round thing as a nuclear bomb.
"Who can disarm it?"
"Only me."
As soon as he hears that, the Joker winces preemptively; half a second later, the masked man breaks the physicist's neck. Of course. How could he do anything else, with a setup like that? Telegraphs the punchline from a mile away. Effective, though, all the same.
She peeks.
She whimpers, "I not have wishes. Can't make them."
Part of him is falling a little bit in love, but most of him is going in quite the opposite direction. This Bane guy has a talent for public speaking, but when you look at his actions, it becomes obvious that this is not someone with the best interests of any part of Gotham at heart. This is a con, and it's a con that's going to end with the city of Gotham becoming a glowing hole in the ground - if the part about the nuclear bomb is true, which he has to assume it is.
Just as soon as he thinks of a plan.
"Okay," sighs Pen. She climbs over the back of the sofa to flop half into his lap.
And then Bane is leaving.
The Joker rubs his face with both hands, hard. A few stray smears of makeup smear further. Now the news people are stuttering some more. He isn't interested. They can't tell him anything he wants to know.
He has to think. He has to—mm. Maybe. Not his usual style, but this is not a usual situation.
First things first, though.
"You get what the guy on TV was saying?" he asks, looking down at Pen.
"...Some?" Pen says. "The thing can..." She snuggles up, thinking. "Like thing hurt Shell Bell? Same word, 'nuke'. Wards better now but only me..."
"Mhm," he says. "He said he'll kill everybody in Gotham if anyone tries to leave or take his bomb away, and he wants to show us something tomorrow. I'm pretty sure that whatever he's doing, killing everybody in Gotham is gonna figure into it at some point, even though he didn't say so. So I wanna figure out how to take the bomb away without him setting it off. And I think I'm gonna see if Batman wants to help me with that."
"Don't know yet," he says. "I think I'll have to spend a night at the old place. And I'm gonna have to, mm, make a call first." He glances into the kitchen. "I'll finish lunch first, but then I gotta go. Will you be okay without me? I'll probably be back tomorrow morning. You can talk to me the magic way if you get lonely or run into trouble."
"Okay," says Pen, in the voice of someone nobly making a great sacrifice.
He hugs her again, then bounces to his feet to finish making lunch. There is plenty to be left over; he barely eats before he scrambles into a hat and jacket and out the front door.
"Bye!" calls Pen. She eats lunch at a more leisurely pace. She watches some TV.
While the news is mostly occupied with discussion of Bane and his threat, several channels do find time as the afternoon wears on to mention that Wayne Tower has been vandalized again: someone spraypainted CALL ME across the back of the building, in black letters outlined sloppily in red over a background of white scribbles. Although the message is large enough to be seen from a distance, no one has yet come forward to report witnessing the crime.
Pen doesn't bother to turn the TV off, but she loses interest after a while. She amuses herself as best she can and doesn't bother Cindy. Eventually she goes to bed.
So he cleans out the fridge, puts on his makeup from what he left here when they moved, dismantles the deadly traps on the front door, and settles in to see what happens.
That is not Batman. He took down the traps because he didn't need them anymore; he didn't expect anyone to actually come in that way.
He gets up and peers through the spyhole to see who on Earth it could be.
