Yeah...I'm pretty sure Zach will be like. "It's fine, I took care of it." When Logan asks what Darren did. 

This is true. They would have to be stupid to back to Darren after seeing how much better they are with Billie and Alex.

I actually see Logan start laughing his ass off at them when they ask her to come back after casting her out. He'll be like. "I don't know what you're talking about. I didn't hear anything."
