According to the sailor, it is pretty much the same on the other side of Caido as it is here. Pretty much did not mean exactly, however, and Rin thought that even if there is only the slightest difference between here and there, that she would have to see it one day. And if it so happened to be exactly the same, wouldn't that be a spectacle in itself? So she looks at him and nods, deciding that, "I think I've still gotta see it," solidifying that nothing could rain on her parade in a permanent way.
Though not entirely sure what spurs him forward, she has the suspicion it is due to him remembering his injured profile. Still, Rin doesn't point anything out, and when he begins walking away, she is pretty surprised that he gestures for her to follow.
Initially, she is only trailing him, but when he asks her what sort of odd jobs she does, she jogs a few steps to catch up to him in hopes of walking side-by-side. "Oh," she starts, realizing that her phrasing was mildly strange. Odd jobs... that could mean a lot of different things that Rin didn't intend. "I can be pretty fast, so I usually pass along messages and letters from sailors to citizens or vice versa." She could, after all, shift into an animal noticeably faster than humans. "But sometimes I'm sent to retrieve specific people or things, run errands, deliver packages-" She pauses. "Nothing illegal, though." She thinks. Honestly, she doesn't really know what the packages or letters or people she's helped are compromised of, but sometimes ignorance is bliss.
