So that's why you asked me if I saw a man in a mask, huh...?

[Things make more sense now. Rin feels glad that Xie Lian feels comfortable enough to share this pain with him. He's not wrong either: struggling together makes heavy weights more tolerable.It's that sentiment that lets Rin speak with a bit more ease, with a bit less weight on his shoulders.]

Then we'll struggle together. If that White No Face shows up, then between the two of us we could kick his ass. And if the demon in my heart gets out and starts causing trouble then I'll trust you to punch him a few times so I can get control back.

Guys like that are scary, but they're not impossible to defeat. No enemy is impossible.
