Yes, that was my thought or rather he was reading that story trying to understand it and was frowning in concentration and puzzlement. I mean, if that really is Snow and it shows what she “did” to Regina and she never quite realised what it was (until Regina tried to kill her, she had no idea she did something to her …), then Henry – not being much older or even the same age as Snow at the time – would have some difficulty understanding the situation as well.
I desperately hope that my convulted sentence is understandable. 🙄
