While there's been no official announcement either way regarding the Season 3 prospects for Marvel's Agent Carter, a new casting item has many fans wondering about the ultimate fate of the series. Per THR, Carter star Hayley Atwell has joined a new ABC pilot called Conviction, in the lead role. Of course, this is just a pilot and the show is a long way off at this point from being considered for a series pickup, but the fact that Atwell is seeking out new TV roles places Agent Carter's future in doubt.
