Bran completely ignored Ella, because she was talking to Lotte like she was either a child or insane and he didn't like it; but losing his temper was not something he could allow. Instead he turned towards her, not making any move to touch her, but not backing away either.
"Lotte," he said firmly (but not unkindly), "It's just words. For some reason we're stuck here and to get out the building or whatever it is wants us to recite a few lines. It doesn't mean anything. Neither of us are actually dying, and you're not causing anyone's death. You never have. This has nothing to do with Erik and Christine. They're characters from a book; separate people with separate lives." He'd lied to her and decieved her, but despite how similar he felt to Erik, they weren't the same. Lotte couldn't keep thinking she was at fault for the death of a man who had been doomed from the start - just like he was.
