Only took a third watch for it to really hit me. But Louis completely missed Lestat throwing himself on the sword during the trial. He admitted to willingly breaking the second vampire law, and that if they're going to put Louis, Claudia, and Madeleine on trial, he should be tried with them.
Lestat knew the coven wouldn't harm him. He was trying to save them. That was why he came. Not for revenge, as Louis thought, as all the vampires there thought. He came to find a way to save them. But Louis was too caught up in recalling his spotty memories that he didn't notice it. Like much of their relationship, Louis wasn't really listening to Lestat.
I know it had to be this way for the narrative, but... Damn I just made myself sad.
