That was my question. So is it possible that it was the ORIGINAL (or the second novel version of) Alicia who met up with Lancelot? That's why the MC didn't recognize him but when he said his name she did? But then Ares is gonna start wondering why she mistook him for Lancelot when she should have already known what he looked like..... However there's a hole in that theory too since I thought she was reborn to a much earlier age than what she appeared in that particular flashback.
I mean I don't know how much the first and second versions of the novel differ but if the age at which the MC was reborn and the age at which her mother left and returned were the same in both versions, six, that doesn't leave a lot of time for Alicia herself to go looking for her mother and meet Lancelot.
wait didn’t she mistake the ML for Lancelot in the beginning? if i remember correctly, it was part of her plot to sleep with Lancelot and eventually marry him to escape the upcoming war. however ML was calling himself Lancelot during the party, so she ended up sleeping with him by mistake. but she already knows who Lancelot is so how could she make that mistake...
