Demons of the Night (2) - S1.E2

In part 2, Mallos and Vashista torment Goodwin and use him as bait to draw in Raphael. The plan succeeds, but only after Mallos has sadistically ripped off Vashista's hand and sent her back to Hell himself. In their final battle, Mallos taunts Raphael with the fact that his daughter Kiyomi is still alive and out there...somewhere. He then manages to escape. Raphael and Sara recover Goodwin, and they decide to make Sara part of their team, bringing her scientific expertise on-board.
