Lol omg yes. Bonus points if he can make his emotion bombs out of like actual smoke bombs for dramatic flair. If he doesn't think of it himself, one of the characters I'm toying with for the future would be happy to suggest it. (Also, just throwing it out there, in February he should play Cupid. In fact, he'd be pretty great around a lot of the holidays...)
She can definitely still feel emotions! It's just mostly the selfish ones. Anger, jealousy, she can care about them but love works differently with her, and she has some small amount of empathy but it's not near to what it should be. Is he capable of inducing emotions that someone has not previously felt/would not be able to feel otherwise? Because that could get very interesting.
Yesss run away from her ghouls and for the love of anything don't drop an anger bomb on her when she's around her corpses XD
