As I mentioned before, Tina's exit is part of a very huge story arc master plan. My guess, the last we'll see of Tina is around the month of May, but I assume her storyline won't be resolved until the end of this year.
Yeah she's cool, i miss Amber though. That girl had moxie. And what happened to Dev? Is he gone now? We rarely see him. And is Ken ever coming back or did they boot him from the show because of the allegations?
