Selfless/Supersymmetry

We’ve got a couple retcon episodes this week, as Buffy tries to answer the question, Who is Anya when she isn’t with Xander? She has over 1100 years of history to try and answer that, but even so, she can’t, and the show does a great job of using the character’s one-dimensionality to explore this in a surprisingly rich way. On Angel,  it’s revealed a former professor is the one who sent Fred to Pylea, and this revelation causes her to wrestle with her traumatic past, with devastating repercussions for Gunn.
