Lee meets Lin, a.k.a. 'The Predecessor.' Part 1 of a 3-part story.
Though it cannot be stated outright in the story for legal reasons, the character of Lin is Linda Danvers, the lead character in Peter David's Supergirl run. When Fallen Angel originally launched at DC, it was often implied that Lee was actually Linda, and many of the series' themes were continued from previous Supergirl stories.
When asked to comment about Lin, Peter David said "Can I say this is Linda Danvers? Of course I can't. However, it's pretty freaking obvious that it is."
Buffy Summers appears on a tv playing a scene from the Buffy The Vampire Slayer episode "Normal Again".
