yeah, i do think they had something and it ended soon enough (or bit before) he and K hooked up. on the other hand Kristen continued to be friends with Nikki - that's the thing i don't get. i mean Rob and her obv had a bad fallout, but Kristen leaving MA (who's Nikki's really good friend from even before the Twilight) and then going for Nikki's ex while Nikki's staying K's bestie is weird, to say the least.
