Before we try to throw Alir onto a dagger 23+1 times, Vanessa is going to attempt to go the non-homicidal route.

She'll try compulsion to subdue him, which is something she could already do using her eyes, but she can go the extra step with some spell-casting to (try to) control him if needed.

If it worked it would be like intimidating him into submission with her power, then compelling his heart-hunger to like...chill out a little (or redirect it if it can't be calmed).

Any effect? Knowing how different things are here I understand if it doesn't work, but she'd give it a shot.
