Sounds like a plan.
So, I think Electro has used up the Soaking Wet Hostage complication, and it's no longer available for you to use (but if it was, and you used it, you would use it at full D8 strength). The hostage may get in Kaine's way for dodging Electro's attack, but after that, he should be able to get over the problem pretty quickly.
Also, what's the justification for the Spawn of Venom distinction? You may very well have one, I'm just asking.
On a somewhat related note, Plaids, since Hercules is in the bank, now, you can ditch the Mass Confusion complication. Herc is now in a less confusing area.
