This is the episode that breaks up Oz and allows Willow to get involved with Tara. One of the most painful breakups on the show; excluding sending to Angel to Hell - Aly and Seth both do a marvelous job.
Naturally, Aly excels when its time for Willow's heartbreak. She knows how to choke up the audience everytime she resorts to tears.
The storyline is interesting in that it gives us a look at a werewolf who not only accepts herself, but revels in the fact that she's savage and free. Interesting because Oz has always seen himself as a human who becomes a wolf, while Veruca's view is that she's always the wolf...her humanity is the disguise that allows her to mingle with humans.
The actual break up of our favorite couple is sensitively handled, taking care to not make it Oz's fault per se. This allows Seth to leave the show with the viewer's positive feelings for the character left intact.
