Kristen Stewart and Robert Pattinson took over the 2011 San Diego Comic Con on Thursday (July 21).

The twosome, who play Bella and Edward in The Twilight Saga: Breaking Dawn, got down to business about what fans will see in the latest installment.

Kristen, 21, shared about Bella’s emotional roller coaster ride, “Really, with everything I do, it’s hard to take myself out of it. I’d been building up to these moments for four years. This one has really cathartic, impactful, huge life moments and they are very rooted in a reality that I can completely see myself in. Anyone who reads the book can imagine it. I do feel like it’s very close to the book, but we also sort of added in some bits. There are some surprises that surprised me too.”

FYI: Robert wore AG “Protégé” jeans.
