do آپ think Sarah's friend Karina should come back in season 4 and if yes what should the episode be about

Carina actually is coming back in episode 4x15. The episode عنوان is Chuck Vs The Cat Squad. This episode should be airing on February 14th (AKA Valentine's Day! and the دن before my Birthday) :)
