To others, it might seem that Marianne and Lancelot didn't speak much, but in that short exchange, both of them experienced the frustration of an opponent they couldn't defeat easily.
Unlike Arthur, who was mostly strong due to his Excalibur.
Marianne Le Fay was an honest-to-good genius when it came to swordsmanship and close combat.
'Damn, that woman was scary...' He thought while holding Morgana's hand to restore the loose ether in his body from the high-speed thought and magic operation to counter her simple greeting.
[Wow... That woman tried to kill you over fifteen times in a few minutes.]
'That's how she is!'
Lancelot felt a strange feeling that she should support him and be an ally because he defeated Arthur. He was sure in his last life she was killed by her half-brother and father...
Something didn't add up, or maybe it wasn't the right time yet.
