Red will walk right up to one of the flyer and stare directly at it. In fact, what's this? He's reading it out loud seemingly not considering that Trip is within earshot-

"For hire. Skills photography, tracking, exorcism. Prices negotiable." He's staring so intently at the flyer almost as if he was considering the contents of the poster before fully turning to face Trip. It's when he saw the younger trainer did he register him as the guy he had seen back during the festival.

Immediately Red's expression lit up before quickly he adjusted his cap, mostly to not make direct eye contact with Trip. He wasn't there to start a Pokemon battle, after all...!
