Ruby died on Season 4 of Supernatural. It's time for Sam to move on.

So new showrunner Jeremy Carver clearly thinks, as he's preparing to cast a new love interest for the hunk of a hunter.

Described in network notes as "brave, sweet, smart and sarcastic," Amelia will be a doctor in her late 20s/early 30s who is introduced on episode three of Season 8. Look for her to be affected by a personal tragedy and initially unsure what to make of Sam.

It's a bit broad and vague, but have at it: Who should come on board as Amelia?

As just announced by The CW, Supernatural will return with new episodes on October 3.

UPDATE: Liane Balaban has landed this sought after role.
