Supernatural Season 9 Spoilers: Lindsey McKeon returning as Tessa the reaper

Is someone about to head to that mansion in the sky on Supernatural? It's possible, as actress Lindsey McKeon tweeted Thursday that she would be returning to the show as Tessa the reaper later in Season 9.

"Off to Vancouver to reprise my beloved role as #TessaTheReaper...Stay tuned, you will all be very excited..."

In other Supernatural news, Misha Collins, who plays the angel Castiel on the show, reveals to the "Spoiler Chat" column at E! Online that the two paths will soon merge:

"Tyler: I need more info on Castiel's return on Supernatural. We've gone too long without our favorite angel.
Relax, you can expect a big 'convergence' between Cas' storyline and the brothers' storyline very, very soon, but Misha Collins previews a conflicted Castiel as he now is the reluctant leader of the angels in the quest to stop Metatron. 'Cas knows from personal experience that when he has a position of power, he tends to screw things up, so he's definitely gun-shy.'"

Collins also spoke to EW.com earlier this week ahead of his great directorial debut episode, entitled "Mother's Little Helper," and revealed the following about Cas' arc for the rest of this season:

"Cas is on his own, continuing to hunt Metatron and figure out how he can get back at Metatron and restore the natural heavenly order," Collins said. "The reluctant leader is something that continues to be a storyline for Cas this season." But he won't be alone for long, as fans "will see him reunite with the Winchesters. Cas will be woven into [the Mark of Cain] storyline. Dean and Cas are going to attempt to collaborate again."
