Maybe she could deduce that he's a werewolf and the possibility of his powers running out past the night would mean we only need to keep him pinned for a bit.

Werewolf are considered fictional creatures. Thus C.A.I.S. would think the whole night thing is fake and she wouldn't be able to figure that out by simply watching a fight in progress. The only weakness I can see C.A.I.S. coming up with is the sound frequencies one since wolfs and dogs can hear more sound frequiences.

Edit: That being said she wouldn't know the correct sound frequience and we don't have anything that could make such a sound.
