No Marian listed though. Which isn’t necessarily conclusive evidence that she’s not around at all, because there are surely Merry Men around as well, and they’re also not credited for this ep either, but may be for a later one. I’m just saying, it seems they’re re-introducing Robin solo.
The shot of him with his bow drawn makes me think he’s snooping around the castle, looking for something magical to help with something or other, when Neal and Mulan show up, (I guess Mulan knows where Rumple used to live, because Neal surely doesn’t). I think he was searching for a way to make a portal out of FTL to get to the land without magic where Marian went pre-Curse, and when Neal turns up looking for the same thing, Robin teams up with them.
