Here's what you can't see in that BD clip vid:
And when the lights went down and the BD clip started, Rob's arm like shot out around her waist and pulled her into him and then they cuddled up onstage for a few seconds. Rob wanted to get off the stage and was pulling her/motioning her but she wanted to watch the trailer (lol) so she and Taylor stood up there craning their heads to look at the screen while Rob would disappear for a sec and then come back on, waiting for her. Then right before the lights came up, Kristen did this little skipping thing and all three scurried off.
