Yet another reason Jillian needs to be croaked. And I used to like her, too.
I love, love panel 4. The way Jillian's hair is flying about was very nicely done.
But yeah, Jillian certainly did cause, or significantly contribute to, Sammy's demise. You can't just fly into the middle of a battle and yell something so surprising. If Sammy is Hagar's chief warlord, which seems likely, well, they're screwed. They just lost a massive leadership bonus--the warlord bonus, the hex bonus, AND the bonus to Sammy's personal stack.
As for Charlie...why NOT piss Jillian off? She's served her purpose--Charlie's goal seems to be not only slap down GK, but also prove to the RCC that he's 'trustworthy'. Both of which seem to be in the process of being completed. After all, Charlie certainly wouldn't have helped defeated GK (and, let's face it, they are defeated, it's just at this point we're wondering how badly) if he were allied with them, and as far as everyone else is concered, Faq simply hired him, and he's not the one who orchestrated events.
Even if Charlie screws the pooch with Jillian, there's just not a whole lot she can do but bend over and take it. She's in a tiny, pissy kingdom that has drained the treasury of a much, MUCH larger (and older) kingdom--her defenses that she can support herself are a joke, and she probably couldn't maintain (or maybe just barely so) the upkeep of the air armada she currently has along with her natural allies, the infantry, warlords, etc. Charlie is footing the bill for her (only) casters, meaning without him, she goes back to zero.
On top of that, she really hates Stanley, meaning she certainly won't turn on Charlie by helping him in the slightest. Jillian can't break alliance to attack either Hagar or Jetstone, else she'd be breaking alliance with Transylvito, basically making her a sitting duck. And if Jillian really does want to croke Stanley, she'll have to stay on with the RCC, who will probably be dipping into Charlie's suddenly incredibly reasonable services after this.
@Ansom not accepting the 'duel'--Sammy wasn't offering, and Ansom would have been stupid to accept. After all, the RCC2 has at least double Hagar's forces behind them. Sammy was fodder to soften Ansom up. He can and did take Sammy out, which hasn't really changed the tactical situation. On the other hand, if Sammy had croaked or even wounded Ansom even more, GK would be in even more trouble.
