Yeah, the dancer droid seemed like a trick gift to me too. I suppose it could have been a simple case of "Feon likes dance, let's give him a mecha dancer," but it seems soooo much more likely to have been a malicious act. Perhaps some kind of secret assassination as some have suggested, perhaps merely a subtle slap against Feon's taste for the imperfectly shaped human dancer, but at the very least, a designed distraction.
And although we don't have any evidence for this, that's not because someone went looking and it wasn't there. Luci, being shut out and taking the snub to heart, just left. Mind you, if she had stuck around and somehow found evidence of malice despite not being any kind of detective, the interpretive dance she would have created to explain this would have been dismissed as mere jealousy.
