I love Delena in Haunted :( I don't want it out yet!

blood brothers...not really any epic delena moments in this one...she's too worried about stefan...

This one I think..I agree with Chryso tho xD

Haunted was a big angst episode for Delena. I loved them in that episode. This episode or Blood Brothers.
