This is certainly an interesting turn of events. The Spider-Rotom flies off and is caught by Bewear. Who apparently can make quick work of the wayward suit because out pops that Rotom, looking a little dazed. There's a high chance that it will just try to possess his suit again so...

"Okay, here goes nothing." Peter pulls a Pokeball out and tosses it at the dazed Pokemon and then collects the suit from Bewear.

"Uh.. sorry about that. It won't happen again." He promises the Bewear. "Well, thank god that's over." Peter sighs, turning to Serena. "Thanks for your help and sorry you got dragged into this."
