'Supernatural' Season 10 Spoilers: When Will Cas Head Back To Heaven? New PHOTOS Hint At Metatron's Arrival

The troubled teen will resurface with Castiel (Misha Collins) in episode 20, "Angel Heart."

A bystander snapped a photo of the two actors on Monday, proving that Cas and Claire's storylines will converge at least once more before season 10 comes to close (see photo here).

The daughter of Cas' vessel, Claire made her first appearance in season 4's "The Rapture" (originally played by Sydney Imbeau) but went MIA until season 10's "The Things We Left Behind" and "The Hunter Games." Now back on the Winchesters radar - and even more traumatized than before - Claire (Kathryn Newton) will somehow be drawn back into world of Team Free Will as Cas' grace continues to dwindle and Dean's battle with the Mark of Cain advances.

Cas feels responsible, and regretful, for how Claire's life turned out, so it remains to be seen who will seek out whom during the upcoming episode.

What do you think? Will Cas go looking for Claire, or will the teen's homeless circumstances lead her to seek help from her new guardian angel? Sound off in the comments below.
