Matter Anti-Matter

@CapricaSeven aka Jane Espenson just tweeted “Mr. Marsters starts work for us tomorrow. Whoo!”, a tidbit that comes as a pleasant surprise.  Apparently Spike, I mean Marsters, will play a terrorist named Barnabus Greeley for three episodes.  Curious?  I am.  For instance, will he be sporting a sassy english accent—you know, the one that sounds like it’s still there even when he’s talkin’ american?  And will he pull a Buffy-esque move as a guest character who ends up staying through not only the entire run of the series, but ascends into the spin-off series as well (and will the spin-off series have it’s own spin-off?)?  The man has some serious staying power. Watch out Caprica!
