Sorry, I'm not up on all the law firm terminology, but you get the point. She's this somewhat high ranking lawyer at the firm yet we've never seen her before? I guess it's possible, but it still seemed strange to me.
Was Monica Potter listed as a special guest? I say Mitra's name but must have missed Potter. I was assuming that Mitra would be leaving shortly because of this (she'll probably leave with the old boyfriend). Personally, I think writing both of them off the show sucks. At the end of the season, they started to develop a little chemistry with Potter's character and Shore. I would've liked to see where they wanted to go with that.
