I'll re-read the rules when I get home. I'm not sure absolutely about Brawn's situation, but the Dire Weasels did CHARGE... and that's the key-word here. I didn't give an AO because it was a charge. Notice the +8s to hit, compared to the +6 normally used, also it reduces thier AC to something even less than normal.
Also, in the case of Mak, his spear is still ready for a charge all of this round, it's a readied action afterall. Until someone charges you, or it comes back to your initiative count, your action is still readied.
And back to brawn, your action hasn't even happened yet. It's still the first full round of combat, and you go last, after everyone else, then you get your FRA.
