The ping of a message appears to the side of his text prompt, and Rinzler opens a new window, glancing over the data. If he's already familiar with the coordinates it maps out... well, he doesn't say as much aloud to Frisk, and that's probably as much tact as can be hoped for. There's a little lag at the instructions, but he does nod in the end, privately appending a note to his internal file. (Knock.)

Preliminary data sorted, Rinzler leans forward, planting one hand on the edge of the wall before he tucks and flips over the pivot point to land in front of Frisk. Ground level achieved! Which also means they don't have to look quite so far up to read his next line.
