Hmm, J with a 'pucker up Buttercup' - type of line as he's lining up a bead with the original Cricket? Oh course, Buttercup herself is busy at the moment, but that might shift Bell's attention to Blossom. The inclusion of the Omnitrix in 'Grim Tales' does have the possibility of opening up appearances of 'Ben 10' characters. Maybe Bleedman and BeeAre would be kind enough to supply a hook-in as to how Mandy acquired it.

Being the skilled operative that he is, Grampa Max would probably say something along the lines of 'since you're here, you don't need a warning' before he opens up with a handheld Null Void Projector. Just because we won't see Ben doesn't mean we won't see the kids Max trained and inducted into the Plumbers (Manny, Helen, Alan). It's not his first fight against children either. Of course, the bad guys still have their own portal.

Cyborgs? Could be right: we know Sam is one.
