In apology for his earlier words, Arthur gives Gwen flowers at the end of "His Father's Son". For me, it's somewhat unexpected how readily Gwen takes him back- especially after the class divide that he brought up here was in fact a huge part of why she was initially reluctant to be romantically involved with Arthur. If I'm being charitable to the characters, maybe something shifted in that unseen year between seasons three and four.

In all honesty, I think it could have been interesting to have Gwen and Arthur stay broken up, have "Lancelot du Lac" play out differently with Arthur upset but unwilling to try to woo her again, something goes down with shade!Lancelot that Gwen feels guilty about (possibly just that she didn't question his return 'enough') so she puts herself in unofficial exile, and then Gwen and Arthur end up actually talking their relationship issues out in the finale so the writers can hit the fast-forward button to her coronation.

Most of the beats are the same, but Gwen doesn't get magically compelled to kiss shade!Lancelot while betrothed to Arthur, with that tidbit never being revealed in-universe even though it was basically every other time a character acted contrary to themself, particularly when Arthur was under the influence of a 'love' spell.

In all fairness, I suspect the writers' intent was to play out the 'classic' love triangle without creating fandom backlash at Gwen and Angel Coulby. Possibly I'm being too charitable, but it does feel like Gwen got magicked so the viewers knew she wasn't at fault, not anyone in the story (besides the villains). Yet it did take away Gwen's agency in the episode, which isn't great either. And Lancelot's, for that matter.
