Teach Grant

The Fringe Division is on the case when severely mutilated bodies drained of spinal cord fluid begin to pile up. After their investigation leads them to a scientist with possible ties to the Z.F.T. bioterrorist cell, they are shocked to discover the identity and motive of the killer. When the kills occur with increasing frequency, Olivia, Peter and Walter go to desperate lengths to stop them.

Barry teams up with Wells to figure out a way to close the breaches, but they are distracted by a meta-human nicknamed Tar Pit (guest star Marco Grazzini) who can transform into liquid asphalt. Iris is concerned for Wally's safety after she finds out about his drag racing hobby. When he refuses to stop, she makes a bold move that puts her in danger.
