Regardless of if they were out of convenience, Mon is an angel, so Ben's behaviour is suddenly way too jealous for a beta like he is portrayed as. It's just my opinion, but hedidn't even know William wronged her, only she bacame a police officer because some guy wronged her, and he doesn't know who it was. I'm sure he heard the rumours about Mon if he was also in Dana's circle. So he's put 2+2 together and his answer is - Monica wants to have the guy who wronged her dick her again?
Good riddance to him Mon, he's unworthy. Might as well get the Gigachad now

It's just a bit too soon.
