Haha, that shouldn't be a problem. Just scruff Kass up a little bit from wandering around Route 1 all day and have her reach the Pokemon Center all tired or something along the lines of that. Kozue's natural kindness should have him approach her to see if he can help. :D
And if you just wanted a reference, this is the cast: Kat [Trainer Kat], W. [Quasar99], Patrick [Degenerate], Roisin [Jim], Fenra [Evkay], Noah [Oni Raichu], Kozue [Phanima], Marcus [Lash], Yaz [yaziyo] and Kassandra [Miss Raichu].
The character's names come first followed by the actual person RP-ing with them, in the brackets. I use this sometimes whenever I forget someone, not that I have mind you! o0
EDIT: Oh and I suppose I should update everyone's positions too; Kat, Fen, Pat, Noah and Roisin are all in the vicinity of Viridian Forest; Kozue, Yaz and hopefully Kassandra should be in Viridian City; while Marcus and W. are freeroaming somewhere between Route 1 and Viridian City/Viridian Forest.
