!SOME SPOILERS AND A LOT OF YAPPING! (From chapter 1 to 3 mostly)
Had to make this into two comments since they were long
As some people mentioned who of the parents they personally like more I'm going to give my opinion on it as well. Honestly? I probably like them both the same but Arthur a little more.
Arthur messed up with not taking care of Mordred AT ALL but the thing is: he was young, Mordred reminded him of the night he had with Morgana and what she did to him, considering that she knew it was Arthur all along and wanted to have child with him for all thr wrong reasons (for them to have the throne, get back the family name, etc. Although she did tell Modred she will love them no matter what they choose which we don't know of it's true, I hope it is) and Merlin had the propecy that their child will be the undoing of Camelot, in some way Arthur does care about Mordred (which we can see if their relationship is good in the latest chapters) but there's also Morgana who is too absorbed in the hate and hurt she's feeling that she isn't even realizing some of her actions hurt her child even though she is trying to protect them, thinking what she's doing is best for them. Example: I didn't say anything and only cried when we had the conversation about Arthur, 10 years old i think? After Accolon was injured by Lancelot, and in Morgana's POV on the start she thought that Arthur is hurting her child while in Mordred's POV we can see that it's actually BOTH of them. Morgana with not listening to them when triey try to say some stuff and Arthur with not being there, Which once he did try to be there Morgana didn't let him (she did afterwards which is awesome and proves that she is trying too) but my Mordred is also kinda really hurt by all what's happening—This playthrough since i have more—so they were confused and once again saying this— hurt. As Accolon said: "Your mother does everything with passion. She loves and loathes with passion. And I suppose I am the opposite, like calm waters, trying to soothe her." I 100% agree with it because the way we can actually see how he helps a lot and makes her calmer and talks to her and Morgana actually listens and tries? Which means Accolon is my favorite and HE IS MORDRED'S FATHER, idc that they aren't blood raleted, he's their father. He cares about them, loves them, helps them and raised them. Let's not forget about that he is understanding, not faulting Mordred for wanting to get to know Arthur/seeing both of them as their father. Anyway either i didn't got the scenes before because I'm playing different or it's the rewrite. If it's the rewrite, even if it's not I've got to say it's REALLY emotional and well-written. To sum it up: Arthur did a lot of things he could have done differently but now he tries to be there, Morgana is hurt and wants revenge and isn't realizing stuff a lot but she tries as well, and Accolon is there, loves them and helps them but did lie/not tell Mordred the truth but you obviously aren't going to say to a little kid that they are going to be the undoing of Camelot. I could yap more about it but i may start repeating myself or this gets even longer so I'm ending this comment here.
