... not many bothered to understand why I'd leave. Often times I was told or asked why I don't come back, I still say Jean is waiting for me to return too even after I told her in letters I wouldn't be, even as Kaeya often times told her from what he said.

(Plus it wasn't his place. She's right about it anyway, he's known it ever since his return to Mondstadt. He wouldn't return to the Knights because it's not his place; him forcing himself to be distant with anyone that spoke to him is part of that too. Because he didn't want them to get involved knowing what he's doing is dangerous.

Risky, deadly even. That target on his back only grew bigger with everything he's done despite the Fatui and others not knowing his identity. With all of it he's been counting on them learning one day that he's the only doing this, that he might in fact be in more danger.

That is the price of his revenge, his complete isolation.

But... with what she's done, with what they've done, it's caused things to change in a way he never once expected. It's why he hopes she can handle the risks, the danger that might perhaps rear its ugly head in by involving herself with him when that time comes.)

... it's why I don't fault you or hate you for choosing your own path and feeling as if it's right. (He can hate the knights but he'll always hold opinions of those in their ranks separate depending on who. So far, Eula's shifted into being more important to him than he expected due to this evening.) And I never saw your last name as a reason to hate you either. I chose to isolate myself, though... as you can see it came with me running myself down as I've mentioned earlier.

(And worrying those who were still there to care for him.)
