"Clary, where are we going?" Jace asks for the tenth time–or maybe the hundredth, she stopped paying attention the second they got to the station and she had to sort out tickets.
"To the moon," she says, absentmindedly, scanning the digital list for the right stop. "In a big rocketship, we're going to find out if it's really made of cheese by trying to set it on fire."
He makes a derisive noise, slumping against the wall next to her like he's got no bones. "Come on, everyone knows humans can't actually go to the moon."
She pauses and turns towards him very, very slowly. "Excuse me?"
He holds her gaze for ten seconds and then loses it, hiking his shoulders up to his ears. "I'm kidding, I know about the moon landing. Simon showed me all the videos about Buzz Legstrong or whatever."
She squints at him and then shakes her head, going back to the screen. "The sooner I get this done the sooner I can pay attention to you instead."
"Or," he suggests, basically plastering himself around the frame of the ticket machine, "You could start doing that now, and we could go home and you could do that all day. I'm much more handsome than the little stick guy there, and I can buy you a smoothie from the kiosk."
She snorts. "You mean I can buy you one. Anyway, Mister," she peers at the little animated name tag, "Tracks? God, where's the creativity. Whatever. Mr Tracks can get me tickets to the special surprise I put a lot of effort into arranging for you, so I think I'm good."
Jace wilts, and then peels himself off the wall to wrap his arms around her waist and look at the processing screen. "Clary."
"What would your astronaut name be?" she asks him, not acknowledging the point of his chin digging into her collarbone.
"My name isn't good enough?"
"Not for going into space it isn't," she says, just in time for the machine to ding and spit out two freshly printed tickets. "I'm thinking... Blondie McBabeface."
He hums, consideringly. "That's not bad. Maybe I should start introducing myself like that."
"Or I can just call you Sweetcheeks and call it a day," she suggests, and can more or less hear him smirk.
"You know what else is sweet," he starts, and she slaps a hand over his mouth, cramming her fingers into it to jab into his hard palate to stop him. It gets them probably an equally strange look from the little old grandma waiting in the next line, but at least she doesn't have to hear anything other than his gurgling sounds.
"Moving on," she says, and drags him off to the gate. "Come on, stop complaining. I've got M&Ms in my bag if we make the train on time."
A bad idea as it turns out, because she always forgets how fast Jace can run. She makes him wait until she gets her water bottle out to ice her shoulder before handing them over.
