It took me a moment since I hadn't seen Martha Plimpton since an episode of SVU to figure out it was Stef from Goonies.
This episode focused on Peter and what he does to help solve cases without his father or Olivia to help him or for him to help them.
Do people even know what mixed cds & tapes are considering our digial age of downloads?
And are we now going to have Fringe posters like the X files "I want to Believe" but instead they say "find the crack"? And who else had a flash of Peter being Walter while he was holding that needle towards Mathis?
