AT the risk of being unpopular I am going to disagree with this set of gifs. I don’t think he was happy in Awakenings. I think he was deflecting and bitter. And I don’t blame Justice for what happened - Justice thought he was helping, their joining was an act of friendship and one that Anders (according to Gaider) doesn’t want to undo.
I get frustrated when people lay everything that happened in DA2 on Justice’s shoulders. It was ANDERS’ anger that corrupted him, not the other way around.
