As for the Wizard being Charming’s father, I dunno. Have always kinda had it in the back of my mind that his father had been a Knight of the Round Table, (Snowing had that big round table they had meetings around, which would be a nice tie in if Charming’s father had had a seat at the other Round Table, and his dragon slaying skills wouldn’t be so random if his father had taught him professional swordplay which a Knight would know, and maybe he thought to use the Excalibur story to inspire Snow because it was a story he’d heard as a child from his dad), and today I settled on a headcanon for how the Wizard could potentially be WW’s father, and if that were to happen, I wouldn’t want her and Charming to be (half) siblings.
David went to Rumple for this idea for the sword remember. As for the round table that was in King George’s castle originally.
Look RH, Red and everyone else is the about the same age this is Once, Uncle Henry could be in current time too as the rest of the group.
Again pointing out that the Uncle Henry in the books was in OZ castle and kept track of all the treasurer. Why would this Gorman guy know about Emma if he didn’t come from OZ?
