Stefan in season 3:
*gone off with Klaus because he sacrificed his freedom and life with Elena to save Damon's life*
Elena, you need to move on. Stefan's gone forever.
Damon, you are so wise and noble. Yes. Stefan is gone forever. It's not healthy for Elena to be clinging to the past. She needs to move on... with Damon.... in his bed.
Damon in season 6:
*quite literally dead*
Elena, Damon's gone, you need to move on.
Stefan, how could you? What a selfish and cold-hearted brother. Damon would never give up on you if the situation was reversed. You're a piece of garbage and Damon is a better brother than you'll ever be.
