Galahad is quiet, absorbing this. Before he came here, he didn't overmuch consider the effect of his mother's deception on Lancelot -- because Lancelot hardly seemed like a real person. Distant and angry and impossible to please, the approval Galahad hoped to win from him back then unreachable; Galahad couldn't have considered his feelings because his feelings were so opaque as to be unimaginable.

Now, even without Claudius there to understand, Lancelot has become a person at least familiar enough for Galahad to see the ways in which he was used by God, the ways in which his life was manipulated, violated, to further Galahad's existence. And this older Galahad, rather than acknowledge the cruelty of it, tried to console Lancelot by reminding him that he was used, that they all were used.
