Rikku has always been tolerant for people being close to her even if they weren't familiar to her because, well, she was like that too. And as such, she acted towards Mjrn as if they were big friends already.

When Mjrn asked her a question, though, she had to think a little. How to explain it well? "You know, the way they see the world. Most of humans feel like they need the guidance of some deity, and they follow it blindly, while in reality you can create your own fate..." She then thought that maybe it's different for Vieras, too. "How do you see those things?" She asked that mostly because of curiosity.
