"I'll save you from the pirates." OMG Zuko is holding Katara and saving her from pirates!
Oh wait, he's actually helping the pirates and kidnapping her.
OMG Katara is touching Zuko! They must be secretly eloping!
No wait, he just betrayed her and helped kill Aang and bring down Ba Sing Se.

OMG they're hugging! Zutara must be coming true! They would never try to fake us out with a preview!
