Swan Song, very ominous title indeed. I agree with the definitions, and would also point out that generally the Swan Song for a person is usually something Beautiful and/or Noble in nature. In this case, something Heroic.

Given that we are seeing Hook's dad filming for this episode, combined with the fact that Killian's name (along with Emma's) is emblazoned on Excalibur, We could be looking at yet another death for Killian. (Not a permanent death, I would imagine, but at least a cliff hanger). But it could be that Killian's Sacrifice is what saves Emma from the Darkness. (Just guessing) We already had a non permanent death for him (even though it wasn't real in the AU). So most likely this time there will be a permanent one. No one knows.
