1. The stationary observer: As expected, he sees Alice freeze at the horizon. What's unexpected is that he sees the horizon much farther than naively expected.
2. The falling observer first sees Alice receding, but then he seems to be catching up with her. However, he doesn't bump into her at the horizon. Although it seems like the first dot is getting closer to the horizontal axis, the release times are getting closer (red is closest, I assume?).
I would add to this that perceived distances are more objective than coordinate distances, as the latter depend on the coordinate system. The 12M distance is a coordinate distance, wich doesn't take into account the "bulging" of space around the black hole. That might account for the 65.73M.
