For me, it’s more about his expression in a couple of the pics, like the first one. Obviously not all the pics were taken while they were actually shooting, but that one seems to be, and he’s looking somewhat distressed, like he’s not looking at the woman he knows and loves.
Maybe she eventually agrees to go out with him, even if she doesn’t have her memories back yet. Maybe after the scene in The Miller’s Daughter she’s at least open to the idea of getting to know him, even if she doesn’t understand their connection properly yet. So maybe she eventually agrees to go out with him and give him half a chance, and they’re meeting at The Rabbit Hole, and when he shows up, she’s not what he was expecting. I just can’t get past that look he seems to be giving her. Things aren’t rosy with Rumbelle if he’s looking at her like that.
