Supernatural Season 6 Spoilers: Is Lenore coming back?

Jim Beaver has posted on his Facebook page that he has been working with Amber Benson. Fans will recall that Amber played the "good" vampire Lenore in the Season 2 episode "Bloodlust." Looks like she will be returning, but as what character? Here's what Jim posted:

Finished day 1 of episode 19, working with Amber Benson. She's a real sweetheart. My Cecily (*major* Buffy fan) would have been so excited that I'm working with "Tara Maclay."

Does this mean Lenore will be back? And if so, will she still be good? Stay tuned; we'll post more spoilers as soon as we get them!
