The fae, with one leg still falling to the ground cannot completely count on his fae balance with a man with more weight than he is yanking him in another direction. Mab's smile is almost hungry as Lancelot manages to throw the fae in the direction of the forest, and the fae stumbles forward, trying to regain his footing and get his hand away at the same time. So long as Lancelot keeps contact with him he can't veil to hide. Predators don't much like fighting on equal footing.

It takes him several steps closer to the forest and then another one as he tries to pull away from Lancelot looking frustrated, the trees rising up around him. The fingers of his other hand curl into a claw and he slaps his had out at Lancelot's face.
