Applesauce penguin, brother.

Damon couldn't tell Stefan his plan because Sybil can't let him physically speak out, so it comes out as that, it's a scene from earlier in the episode.

Hahaha! I replayed that four times before giving up. I definitely heard the "applesauce" but couldn't even decipher the second word. "Applesauce penguin" works for me-- great alterna song title?!

As someone who is very much IN-touch with the TVD world, I can make NO sense of it...other than Ian garbled a line(???). I have noticed him adopting a much softer way of delivering this season, I presume it's a choice to go with Damon's defeatist attitude.

Yeah the siren made it so that Damon cannot even formulate the words in his mouth when he tries to tell another person about her plan. He explained this to Stephan earlier in the episode by saying that "applesauce penguin" is what his words sounds like. I think "applesauce penguin" may be how linguists describe gibberish.

Maybe it's an anagram. Maybe rearranging the letters will reveal something.

Applesauce penguin, may refer to Marry Poppins, the Nanny, dancing penguins.
Haven't watched the whole move so, applesauce is still in question.

We're all on our way out, act accordingly.
