... Kinda. It is the reason she would need Ethan again, and I imagine that Tanner would have been a long-standing partner. The mob boss just seemed like a good connection to the first part of the story, to make it less of a random element and tie things all together in a nice way. We could probably work around it, but why would she need/want Ethan then? And why would he go along? I kind of assumed since Bree is the one who's been working the case for years, and she is the one who knows the most about it, she'd be kept on it until they could find a solution, I guess. We can probably work around it, though, if it wouldn't make sense to include it.
