C'mon, Titanic wasn't that bad. It did at least have Kate Winslet's rack. (Well, in Dean's opinion of course.)

The idea that Balthazar would go back and change history because of his dislike for the 1997 film was amusing. He would be pompous enough to go through with such an act, but it was the fact that he was following orders that was truly surprising. Especially orders that came from Castiel.

So, no, it turned out that it wasn't really because of Celine Dion's song that caused the famous ship to avoid the iceberg, but rather an effort to gain more souls for some mysterious war machine. What is the war machine? Well, it seems to be just as secret as the soul collecting and the battle in Heaven itself.

Castiel has remained extremely quiet in terms of the angelic struggle. Plus, not getting any chance to witness any of it makes me wonder what is truly going on. This war has certainly changed Castiel and the types of decisions he has come to make. After all, altering the timeline seems like a drastic move. How is he really handling the situation?

Yet, what happens if he does win the battle? Are fate and destiny thrown out the window? Can you really choose your own path to follow? The domino effect of ideas seems endless, especially when going back in time to change history now seems to be possible. Let's not even get started on time travel rules.

The introduction of Fate, while clever in the Final Destination sort of way, does beg the question about the roles of particular supernatural beings. Does she even have a purpose anymore? Does a character like Death or God or even the Angels? Where is the line drawn or has the aversion of the apocalypse caused so much chaos and change that the line has become completely erased?

While I was pleased that Castiel garnered more screen time and offered a slight reveal at his agenda with the soul collecting, this episode lacked a sense of urgency. Sure, the new timeline offered "what if" moments, but the danger of Fate never seemed imminent. 

Even the return of Ellen felt wasted. It was a fun idea to pair her up with Bobby and offer a compassionate side to the grizzled character, but she could have easily been replaced with any other character. 

The typical Supernatural spark just didn't burn as bright in the episode.

That's not to say that there weren't great lines from the brothers or jokes about "too soon?" As always, the music choices fall under the fantastic category fitting in so well with the specific moments of the show. From "One Way or Another" to yes, Celine Dion's "My Heart Will Go On," the music added to the humorous moments.

After a tremendously long hiatus, I was expecting more of a bang from the show's return. I have a feeling though, that as these final episodes wind down, things are going to get kicked into high gear. I still have no idea where everything is headed, but I can't wait to see how Eve, the war in Heaven, and Sam's patched up soul will culminate together.
