Maybe that’s why they’re constantly separated? The writers are trying to keep the show family friendly. It would explain why RumBelle scenes always have a cutaway at the end of them, they’re not allowed to show how the scene progresses further.
I think most likely you’re right. We got Regina and Graham but it was to demonstrate Regina using him against his will–and of course Adam says we’re interpreting the scene, for all we know they could have been playing cards . Snow and Charming are married so it’s “family friendly” (which I find hysterical given that this show is based on a curse that required patricide and black magic and has so far seen murder, adultery, fornication, rape, patricide and teenage pregnancy)
I just hope that this is the last separation. Ever.
