Ah, OK, fair enough. Well, maybe he'll get some ideas for use on Forest
As for Sakura, well, you said before that Sakura's shadow magic (at least her familiars) is one of the few things that could probably defeat Tom. So, yeah, it figures he'd be worried.
Also, if he's weak to ghost types, could he do anything to Rider (especially in spiritual form)? She
is technically a ghost, after all....
