So I never noticed something but when I was watching the performance of 'Bad' by the Warblers and New Directions, Sebastian looks genuinely upset that Blaine was hurt. But what gets me more is that in the end you can watch him repeatedly glance up at the Warbler beside him and on his other side in the corner of the screen you can see someone grab his shoulder trying to pull him back to get out of there. My theory is what if Sebastian truly never wanted to run and just became a further bitch because he felt bad for what he did. Like what if the Warblers got frightened about the trouble they could be in and left in a hurry and dragged Sebastian with them. Because the look in his eyes tells me he did not want to leave.
