Dragox struggles as he is grabbed by Alger and then wrapped in vines.  He tries to get out but stops when he sees how big the battle it.  If he did get out he might get dragged into the battle and he didn't want that.  Again, he had to wait for his fate.  He feels himself then dragged out again into the open by Alger.  He just sits there and doesn't say anything because what he wants should be obvious.
