Aint-it-cool-news.com has revealed how Spike joins the cast of Angel.

In a report about the casting of episode two of the fifth season, the Aint-it-cool-news.com site reports that Spike will come back as a sort-of ghost. That's not all; he will also be stuck to Angel.

"Spike's a dang ghost! Well... A major character in the episode will refer to Spike as a ghost - close enough, anyhow," writes the site's mole, Hercules.

"Cleavers pass right through Spike, as do doors and walls. He mocks Angel incessantly, and Angel has no means to escape the ghostly taunting!"

The episode, written by David Fury and Ben Edlund, also sees a deepening in the tension between Angel and his new employers, Wolfram and Hart. Angel returns to the US network the WB on 1st October at 9pm.
