Julie McNiven

We're only two weeks into 'Supernatural's' winter hiatus and many self-confessed Super-fans are already feeling separation anxiety; lucky for you, Inside TV has an exclusive spoiler fix to whet your appetites before the Winchesters make their ass-kicking return in an all-new episode on Jan. 21.

We recently caught up with 'Supernatural's' most heavenly creatures, Misha Collins and Julie McNiven, to find out what we can expect from their angelic alter-egos next year. Fans of Collins' enigmatic Castiel shouldn't get too excited, though; heaven's latest dropout can't tell us too much about the first two episodes after hiatus -- he isn't in either of them!
