Thug 2 is dead, killed from getting hit by 2 of Ahri's spells.  Thug 3 is the one you hit with your mace, is blinded by Ahri, missed you with a melee attack, and moved to provoke an opportunity attack from you.  Thug 1 is Marc, and he hit Zitka with a melee attack and ran.<br/><br/>As for the spell, if I'm reading the description right, you don't cast it as an immediate action.  Instead, you cast it as a standard action against a specific target, and then it gives you the option to use an immediate action to redirect an attack to yourself.
