And not just him showing up, but the claims that he was fired and suddenly we got "oops he was there all along," like he was kept in a glass case marked Frankmergency. I wonder if Mulcahey was being undermined from the start as Frank didn't want him, like what Paul Rauch may have done to Claire Labine at GL.
Absolutely. I know some fans were disappointed because he wasn't thrown back at Sam and Liz, but even if he had been, that ship has sailed. You can't rely on 20-25 year old memories. And the future scene the show could have built up, like Trina or Cam, the show has no interest in.
Maybe they can dredge up more relatives for Carly and hope they luck into finding wonderful actors as that is seemingly the only path the show has these days.
