To fill out this episode's time slot, there are numerous minutes of film used in previous seasons. Been there, seen and done that already. Watching Nora and Flash in the speed tunnel, slowed down to see their hands pumping up and down as they're running, is hysterical. That "time wraith" is incredibly bad CGI and it's another "bad guy" rehash. Nora continues to be trouble, always opening her mouth when she needs to be muzzled. The only good part of this episode is the acting of Tom Cavanagh.
