I'm going to say it. I don't really like Tank as a character. He's that guy who seems like a "nice guy," but really, the organization he belonged to did some really ridiculous things, and he continued to belong. Plus, his silent treatment, when he was angry at Bay, was really not okay, especially when she didn't really do anything all that wrong. He went into the relationship knowing Bay had feelings for other people. It was a gamble. It didn't pay off. The new situation, with him dumping the fraternity, despite that fact that she didn't require it, reeks of the potential for emotional blackmail. If he did it for himself, I hope it turns out not to be an issue in the storyline. The one thing about Bay is she falls for emotional blackmail ALL THE TIME. It's the one thing that annoys me about her.
Speaking of people who fall for emotional blackmail, Regina needs to slap her mother silly. Her mother may have been right about the entire situation, but the individual ethics are complicated for Regina. No wonder she's got problems. Her mother basically accused her of sleeping with her boss and then pushed the whole "You fight!" nonsense on her, not even considering her daughter's financial ties and what that might do to her. Now, she's in danger as well. Good going, stupid mom. (Not that Regina is without blame. Obviously, she was an idiot to get into business with someone she didn't know well.)
