Oz (Seth Green) returns. Having traveled widely -- he mentions Tibet -- Oz has discovered how to control his werewolf transformations. Willow's (Alyson Hannigan) joy over his return is compromised now that she loves Tara (Amber Benson). Seeking advice, Willow reveals the true nature of her relationship with Tara to Buffy (Sarah Michelle Gellar) -- up until now she has kept her homosexuality as secret. Meanwhile, a commando is attacked by what he assumes to be a werewolf. Oz is subsequently captured by the Initiative. Surprisingly, Spike (James Marsters) leads Buffy into the Initiative compound to free Oz. More surprisingly, Riley (Marc Blucas) helps liberate Oz, subsequently severing his ties to the Initiative. Now, with her boyfriend AWOL from the Initiative, Buffy feels free to reveal her past relationship with Angel (David Boreanaz). Elsewhere, Adam (George Hertzberg) offers to remove Spike's anti-violence chip if he assists in his plan to unleash worldwide chaos.
