Okay, this is just a note explaining something to everyone who begged me to not make Regina a pedophile.
THIS IS NOT A PEDO STORY WHAT THE ACTUAL FUCK
Regina is NOT looking at Henry in a sexual way, she is NOT considering being with him in a sexual way (or romantic way), she's conflicted because she can anticipate what he'll be like as an adult, and the feelings it generates are not entirely maternal.
Regina. Is. Confused. Henry kissing her introduced a concept that hadn't even remotely occurred to her, and now she can't get it out of her head.
Please remember that these three stories take place in a span of less than 24 hours. NOBODY has had proper time to analyze their feelings and responses in any significant way.
Be aware that the endgame is to have Henry and Regina together romantically and sexually, but that's not going to happen until Henry is of the age of consent, at the earliest.
That said, Regina has been introduced to a new concept, and she IS going to think about it - in a future context. Henry as well has been introduced to a new concept, and he will also think about it as he grows into his sexuality.
But for fuck's sake, Regina's not a perv and she's not going to molest her son (although he would be rather happy if she did, just saying)
