I had assumed that Albus, Samuel and possibly Gov. would burst into the bar to confront Mr. Cobalt.

I don't expect it to happen, but I think it'd be pretty funny if Jack got killed in the ensuing crossfire and then we spend the rest of the RP thinking we're completely up shit-creek because we just killed the player character, and they're usually the only one who can get things done. Then again, he could just reload his last save. :V
