Charm Monster and XP rewards

[RoboEmperor]

So lets say there's this big bad fighter and you charm it. You won the encounter and got a fighter cohort, so you get the fighter's CR XP.

So then lets say during a fight, the big bad fighter got hit by a dispel magic and now with the charm monster gone, he tries to kill you. You then immediately try to re-charm him. Upon success, do you get the fighter's CR XP again?

Also, do you split the XP rewards on encounters you won with the charmed fighter with the charmed fighter? What if the fighter was a monster with 0 class levels, and has an ECL of "-"?

You don't split XP, because you're controlling the Fighter with a class feature so it's already factored in to your ECL. You don't get new XP when a dispel makes it uncontrolled because the Fighter's presence in the fight was due to your opponent's dispel, so it's factored in to their CR.

You get XP for overcoming an encounter.

Charming the Fighter overcame the "Fighter" encounter, assuming that the actual job wasn't "Assassinate the fighter so that his younger brother can inherit his noble title" or the like.

The second encounter is the "Wizard" encounter, you only get XP for it when you overcome the entire encounter. That he dispelled the Charm on the Fighter and the Fighter started fighting you doesn't make it another encounter or push up the Encounters CR (as that is calculated before it ever starts).

Alright thanks for the clarification :)
