Why are Damon and Rebekah on the same side of danger in The Vampire Diaries season finale?

The last time viewers saw these two, a scorned Rebekah (Claire Holt) was torturing Damon (Ian Somerhalder) for using her (i.e. sleeping with her) so that Sage (Cassidy Freeman) could read her thoughts. But it seems in our exclusive look at the season's final episode, "The Departed," that the two are together, both shocked and terrified, of something -- or someone -- greater than them.
