There was at least two minutes between Finn flatlined and Sheila, brought him back, with the shocks to his heart.
Usually after 30 seconds, the doctor gives up, and signs the death certifacate.
Well to sum it up, will a revived Finn, not remember any memories, and Sheila has a blank slate, to influence Finn, against(the dish rag whore), Steffy.
Sheila can’t brainwash Finn now, as he remembers what happened. Ah, and the barf-fest of Fake Ridge going back to the Slut from the Valley...
