The problem is that Stanley has no way of paying upkeep for anything, including himself, without GK -- he'd have no income and he
can't take his existing funds with him.
In any case, it looks like Wanda just fell flat on her face while Sizemore's stock rose quite a bit (of which I approve; I find him to be the most generally likeable character on either side). Parson's situation is a bit murkier. On the plus side, he also expressed skepticism about Wanda's (over)confidence; on the minus side, his complete dependence on hiding the wounded dwagons without any backup plan whatsoever (e.g. the idea some folks had of mixing in a few healthy ones) in case they were found did make this fiasco possible.
