You know what’s going to be beautiful though, is when Regina actually warms up to Robin.
I can imagine Robin walking on in Regina crying over Henry and excusing himself, “Pardon me my lady, I’ll give you your privacy.”
"No, stay. Please?"
Robin will be so surprised because Regina actually WANTS his company?! But then he’ll look like a little puppy because she’s finally being nice to him and he is going to eat it up like cake.
