Lex raised an eyebrow, and almost wanted to tell her there was nothing to apologise for. Instead, he sighed.
"It's not your fault, Liz. You didn't do anything to me," he said softly.
"No, Lex. We're not kids anymore," she said with a hint of more vigor in her voice. "After a certain point, we have to stop blaming our parents for our own misbehaviors. You found me, rescued me, provided me with a safe place to hide from everyone pursuing me, and even provided me with the most incredible partner for my cultivation, and all I did the whole time was throw a tantrum like a spoiled child.
"I admit, I spent too much time on my own, running, so I felt unsafe in other people's company. It's not an excuse, it's just the way things were. But if we expect other people to behave more maturely, and if we expect the best from everyone else, then we too have to be the best. You treated me like your little sister, and I took that for granted. So I apologise."
