- Why does Nadia think that she remembers Horse, the bum. Was this ever resolved?
- Not really, but we do get a possible mundane explanation when we see that he's a former tech luminary, so they could've crossed paths in the industry or she could've watched a video of him giving a talk.
- Given the heavy use of metaphors on this show, she probably thinks she recognizes him because he is a literal possible future for her, having worked in a similar field, dealt with similar drug problems, and was presumably unable to work through his problems, which has led him to be a Cloud Cuckoo Lander homeless guy. Nadia dies in many different horrific ways, but she is particularly disturbed after freezing to death with him, probably because it hits too close to home.
