As Peter can he pulls Stiles closer to him and aims for the surface. His mouth and eyes are full of seawater so he blindly grips the first rock to pull them out. He coughs, taking a deep breath and realizes he can smell these fuckers now. Their scent is thick all around the cave, signing that this is their territory and Stiles and Peter are trespassers. No, not even that. They are dinner.

They are excited. They have a good prey in front of them and that makes them bolder than they would be.

Peter snarls, looking over his shoulders to see if any of the mermaids would try to launch at them.

"Stiles, are you okay?" he asks through his fangs, his arm still holding the boy tightly to him. "There's at least five in the water."
