[Awkward past discussions, huh. For all Karkat doesn't know the one she's talking about, he should smell about the same age as she saw him last. Somewhere around that range anyway. Can she smell that?]

You're the one who just showed up like this. And don't tell me I need to fend for you. It might be forever since I've seen you, but I have not come close to forgetting how hard you drub with your cane. If anything, it's about time you showed you cackling maw around here.

[He steps closer now, more within casual conversation range than oh-hey-you're-here-and-I-just-spotted-you distance.]

I'm going to take a guess that you don't remember your last time here since it's been nearly a year in earth time. Have you read up or asked around about this place or am I going to need to give you the info dump?
