The WB and UPN will apparently allow a crossover between the frog network's Angel and the smackdown network's Buffy the Vampire Slayer if Buffy ends this year, as speculated, sources told TV Guide Online. Angel (David Boreanaz) would appear in the series finale of Buffy in May, should the series end its run then, the sources told the site.
Boreanaz wouldn't confirm the crossover, but he did tell the site that "fans would enjoy that. It would be really nice for them." So far, no decision has been made on whether Buffy will end this year, though rumors of a crossover lend weight to that speculation.
SCI FI Wire earlier reported that Buffy's Alyson Hannigan (Willow) would cross over on the March 26 episode of Angel.
As far as the future of Angel, a WB spokesperson told TV Guide that a decision will come in May. Boreanaz told the site that he is "confident that we'll have another season. I think that the show has done remarkably well for the network, and we've proven to have a [loyal] following."
