Plot hole: When Delila finds out who Jimmy really is, she takes his tuxedo and is apprehended by the bad guys. She then turns on her homing device on her necklace. The office says it will take 20 minutes to get to her. From that statement to when the CSA finally arrives, Jimmy has time to go to Devlin's, write him a letter, discover water striders, find his suit, and get back to Delila and fight the bad guys. THEN CSA shows up. The timing is really off.
Plot hole: Near the beginning when the bad guy is testing out his "new formula" on his employee, his explanation of how the bacteria worked could not have caused the effects seen on the man. Genetic material couldn't be incorporated into the host that quickly and besides, pumping electrolytes into the bloodstream may cause death but that would not remove any of the water - it would still be present in the cells and so the poor chap wouldn't be turned to dust in that way.
