The fight is unexpected and quite awkward. It is
possible without luck or cheesing it (I'm not especially good at either) but it's definitely one of those late game encounters (at least late in terms of what we have) and requires some careful manoeuvring, or at least separating your characters and putting the couple that aren't Lae'zel and the PC into advantageous positions.
Don't go there. It's neither helpful nor amusing and isn't welcome here.
