He might be hired by some shadowy figure to capture Flash in order to lure Spider - Man into a trap. There could also be a group of alien invaders who mistake Flash for someone important and Peter has to save him from their clutches.

It could also be that Flash accidentally stumbles upon a dangerous experiment and Peter has to save him from the resulting chaos.
