Oz returns, but there is so much water under the bridge since he left. Willow has gone through the confrontation of loss. She has met Tara and has feelings for her. She has given up on Oz and here he is. He has taken care of his werewolfism except under negative stress. No more Mr. Moonshine. He feels nothing has changed but even when he first sets foot in Giles' place, there is a heaviness. He is captured by the Initiative Gestapo and immediately subjected to torture, without any chance to explain himself. Riley and Buffy infiltrate the place and manage to get him out. While this is going on, Spike and Adam seem to have an alliance going. Adam needs to eliminate Buffy and gain more knowledge. The episode ends with Riley on the verge of a court martial and Oz leaving. Perhaps for good. This episode is setting up the last series of events in this season. Nicely constructed.
