Corrected entry: Cordelia says in the episode 'Awakening' that she has encountered the real Angelus when he changed in Sunnydale, but during the episodes after Angelus changed in season 2 of Buffy the Vampire Slayer she never actually saw him, just heard about him.

Correction: She further clarifies in Awakenings that she saw everything he EVER did (as Angelus) in "virtual wide screen sense surround sound during my tenure in floatyville". She saw firsthand what he was like. Also, on Buffy, Cordelia spoke often of the badness of Angelus. Cordelia did actually meet Angelus in the BTVS season two episode "Killed By Death".
