(I messed a few thing up. Ugh)
Wasp 1 charges Serias and 2 charged Grizz. So, wasp 1 took the Ice Ray damage. Grizz took his first AoO against wasp 2, which missed. So wasp 2 is slightly less injured, but it still looks pretty messed up.
Grizz is also entitled to an AoO against wasp 1, before it attempts to sting Serias -> d20 + 4 = 10, which misses, but gives Grizz 8 temporary HP (although I think these are lost at the start of his next turn, which is right now).
So, I think that gets us up to speed.
Grizz! You're up!
