We have Heather in SM. Lets have an opportunity to ghoul in each part of town (Humanity gain). Get a little more money, etc.
And if you get more than two you get Masquerade breach, 'cause someone was talking.
And you get a mail to get rid of the chatty one "or face consequences".
So you can just plug one and be done with it (with a possible another breach later on and another mail,...), find the one via dialogue (Dominate, Presence), or just get rid of all of them.
Yeah, I know...
