Uh...yes and no. We met the last time you were here which...you don't remember for reasons nobody has an answer to yet. It just kinda happens, people come and they go and sometimes they remember things and sometimes they don't. [He shrugs.] So don't worry about it too much, it's completely normal for you not to remember this world.

[Or, by extension, him.]

All it means is that we just have to reintroduce ourselves! [He beams.] I'm John Egbert.
