[UNRECORDED]

 There isn't a whole lot Walter knows about birthdays. He's got the basics down: some kind of gift, maybe, a cake or something like that if you can afford any of these things. But birthdays have always been a pretty foreign concept he's mostly just... gone along with, when it comes to friendly group of fellow Victors. They're just not things he thinks much about, really. Finding out he'd missed Caro's... well, that's a problem only because it's Caro's. But clearly they erred somewhere with the mention Caro's birthday.

He takes a moment to actually vaguely clean himself up before dragging himself out of his compartment on the train. He's going to be very, very glad when this goddamn tour is over, not just because of how awkward it is to visit Caro. It's so much easier when he doesn't have to dodge prep team minions constantly. He's lucky enough that he escapes their annoying attentions... this time.

He only hesitates at her door briefly. She's upset but upset is hardly enough to deter Walter; it's more the birthday thing. He doesn't know what to say to that. He'll improvise, though, as usual. After a moment of getting his shit together he raps his knuckles against the door. "Hey, sweetheart? Mind if I come in?"
