The first attacker fortunately fell as the words startled him. Since the threat had been for the moment nullified until his polymorph wore off, he let the protective barrier fall away. He was quietly surprised to realize that the one he'd defended was a troll and he wondered if the trolls could also have decent members of their race or if he was about to end up facing two enemies here shortly.

"Sorry. I was just trying to help."

As a precaution he reapplied the polymorph spell to the flying creature currently being landlocked. At least it would give him another precious minute if the troll did attack him.
