"Storylines that have been developing throughout the season will come to a dramatic head this month, such as not-to-be-missed episodes of BUFFY THE VAMPIRE SLAYER (8:00-9:00 p.m. ET) in which Dawn discovers she is The Key on Tuesday, February 6 and Spike ( James Marsters) professes his true love to Buffy (Sarah Michelle Gellar) on Tuesday, February 13. BUFFY's Tuesday night companion, ANGEL (9:00- 10:00 p.m. ET), delivers a memorable two-part story airing on Tuesday, February 20 and 27 in which Angel ( David Boreanaz) succumbs to Darla's ( Julie Benz) wiles but his descent into darkness ultimately drives him back to his crew who he finds may not want him back."
