Breaking Dawn Part 2: See Jacob Meet Renesmee
06/23/2012 AT 06:00 PM EDT
Because of a werewolf-related process called "imprinting," Lautner's Jacob is irrevocably (as Bella might say) tied to the child (played by Mackenzie Foy). Jacob will fill a protective, older-brother role to the child until she matures.
The kicker? Renesmee grows rapidly, and will appear 17 when she's actually only seven years old – something readers don't see in the book.
As Lautner said, "creepy."
"Everybody likes to tease me about it," Lautner told Entertainment Weekly. "I laugh along with them, but it's important for me to keep in my mind that it's as simple as a lifelong bond. It's not nearly as creepy as everybody likes to joke."
Not to worry, though. Jacob and Renesmee's complicated relationship will get less icky during the course of the movie when they have to fight, along with the vampires, for Renesmee's right to live. We'll have to wait to see those pictures, though: Twilight: Breaking Dawn Part 2 isn't set to arrive in theaters until Nov. 16.
