Red tries to take this opportunity to get rid of the remaining webs. If they would get tangled with his wings mid-air, nothing would stop him from plummeting to his death.
Now that Red made the giant tremle in his boots from his might, he can probably take a breather before deciding what to do next. ...There is something weird about this human tho. He doesn't seem like the monsters described in the old legends. It can all be a facade tho, Red cannot afford to lower his guard.
