as always when everyone has to enjoy a party and have fun bonnie is not even is the episode...they always bring her back to use her magic and ssave dopple(elena) and evryone in the town.....
even though damon and stefan have their differences, anda can clearly tell sejak the look on damon's face when he saw his brother in pain, and the way he wanted to kill those guys for hurting him, that he really cares for and loves his brother
