You’re welcome =).Napoleon loved his son, he was a devoted father to his son, imo he was a better parent for his son than Marie Louise (who was very cold and selfish with her son). In some of Napoleon letter, one can notice that there are reports of his son condition that appear frequently. And at the hundred days, even if Marie Louise wanted to go back to France, I don’t think her father will allow her to go (and not to forget his plan to introduce his daughter to Neipperg to make her forget about Napoleon). Napoleon II very impressed by his father, and he considered him a role model, he was very proud of his father accomplishment, and he never forgot him (he even cried when he heard about his father death). And due to the fact that he had a terrible relationship with his mother (she didn’t care about him after moving to Vienna) so maybe in his mind he blamed his mother for abandoning his father and it was her fault why he never reunites with his father again, which raised the what if questions about how his life could become if he stayed with his father. I find Napoleon II very fascinating character, he was very handsome, and one can only wonder what he could achieve if he didn’t die so young.
