From EW.com:
‘SUPERNATURAL’: A TITANIC-SIZED TWIST
Has the wait been long enough for you? Well, lucky for you, the first new episode ofSupernatural in six weeks is all you’ve been waiting for — a little mythology, a lot of one-liners, and a heck of a twist.
In the April 15 episode, titled “My Heart Will Go On,” Sam and Dean find themselves in an altered reality where everything — from the not-Impala they drive (horror!) to the career of Celine Dion — is different as a result of the Titanic not sinking. But once Supernatural fans get a glimpse of how the ship’s safe arrival to the U.S. affects the world, you might find yourself wishing, like Balthazar (who’s behind the altered world), that the ship never sank. Particularly when you see the circumstances under which Ellen (Samantha Ferris) returns to the fold. If you, like me, bawled like a baby when she and Jo (Alona Tal) were killed off last season, you might shed more than a tear during this episode.
Also great? Many bromantic moments between Dean, Sam, and the “dirty-trenchcoat-wearing angel who’s in love” with them. Not my words.
