I always assumed that Gaspar was to find out about ZEAL before the jailbreak...because, as I said, my Gil (and his Magness crew) was supposed to be coming from the EoT.
Also, I figure that after Argus, Sigma & Gil get to Keystone (I'm against Flea making iit myself...), one of two things could occur...Both being relatively the same and depending upon what Gil tells Marcy & Elle to do (I'm for the first).
1. The three of them find one (at least) of the other characters from Keystone and that person joins them (perhaps on suggestions from Gil who knows 3+1 or more=EoT).
2. Gil splits off back into his own adventure (and to reunite w/Marcy & Elle) and Argus & Sigma find at least two of the other characters...
Like I said, I'm more for 1 because I want Gil to go back to the EoT where he'd have left Marcy, Elle, & my Glenn. Glenn will stay behind as one of the heroes for Gaspar...
