Ashley Greene and Jackson Rathbone touched down in Vancouver together earlier this week, and it looks like the twosome are enjoying more outings together. They were spotted on a walk around the city yesterday during the hours they weren't needed on the set of Breaking Dawn. They've been north of the border, logging their very last days of shooting the Twilight series, with costars like Kristen Stewart and Kellan Lutz. Robert Pattinson, however, isn't with the gang, since he's off promoting his soon-to-be-released Water For Elephants. Kristen Stewart actually left Vancouver last night after wrapping up her portion of the film. It must be a bittersweet period for the cast, as they've spent so much time working together on the movies for the last couple of years.
