Robin finally got to met Regina’s other half and it looks like the two might get on like a literal house on fire. What do you think Dark Robin and the Evil Queen have planned for Storybrooke?And can they find happiness together or are they too far gone down the dark path?
To me, it looked like Robin was disgusted by the EQ, due to his recoiling body and grimace on his face. It would be very strange to see him go from that to a steamy hook up. The EQ would be genuinely in him and perhaps even protective of him (as foretold by Regina’s dream a couple of seasons ago), but I am not sure if he would be that interested in her.
However, I wouldn’t be surprised if the writers have them do the dirty, or for Robin to use the EQ in some way via doing the dirty.
