Robin hasn't been spotted since 5x16 and he's missing from both group shots for 5x18 - either he left the underworld (with Baby Hood....?) or Zelena's off messing with him again.

Rumple & Belle are probably off on their own in the UW with a separate plot line, so I don't think the fact they're missing is that out of the ordinary. In fact, I don't think there have been any reports of Rumple with any of the other mains since 5x13, so he's going to busy doing his own thing. Maybe he got them both out of there in 5x17? Idk.
