There's also a possibility that the troll wasn't attacking Hekasan, but someone else, looking for Argath. Not finding him, he threw suspicion on him, or on Sindin, or on Gabriel. It's a lot of roles, but it's worth considering. You could, of course, play it super safe and block Hekasan. But that doesn't necessarily mean I'm right, does it?

By "block," I mean cast Hive.
