"FBI" hit the ground running with Season 7 on the TV schedule, and the first order of business was setting up the exit of Tiff after news broke over the summer that Katherine Renee Kane would not be returning as a series regular.br br The seventh season so far has honored how much Tiff meant to Scola as her former partner in particular, as the search is on for her replacement. Now, the actor who had been cast as a series regular to replace her has already been cut before she even debuted, and the move reminded me of what showrunner Mike Weiss told us ahead of the premiere.
