I love this so much. Thank you for sending this take/perspective!
Regarding the “opposites attract” of Galahad/Mordred: the difference between them is not their actions, but how the narrative frames them. Both are bastards with daddy issues who put place events calculated to end up destroying everything that their fathers ever worked for. The difference is that the narrative directly tells you that that is what Mordred is doing.
