I mean, if we're going by [i]purely[/i] chronological post order, Victor should probably have reacted to seeing at least one of Toshi, Tilly, Risette, Yuu or Ryuuichi leave the group and wlak off into the habitat before he ran off.

Of course, this [i][b]is[/b][/i] Victor we're talking about. And it's also completely fair tos ay that he just didn't notice any of them leave the group, as he was way too busy being dramatic and lost in his own little... Uh... Self-delsuinal adventure of re-catching his starter...?

So, really, I - for my part - feel that it's fine either way. If you wanted Victor to have reacted to any of the other trainers leaving, just edit soemhting in. And if you feel that Victor wouldn't have noticed anyone leaving, because he's Victor, then that's fine too. :)
Others may have other opinions, ofc. ^^
