Claudius laughs, not surprised at Lan Wangji's accuracy, but suitably impressed. "Galahad," he says, "is a menace. None would think it of him, particularly if they met him back when he was chaste and would blush at the smallest insinuation of being otherwise. Know'st thou, I think I remember Wei Wuxian saying something similiar. At the talent show: no one back home would ever believe me that Hanguang-jun is so unreasonable ..." At this point, he's entirely teasing. He knows Lan Wangji doesn't remember that part of the talent show. He neatly pulls out the sleeves of his robe, seeing how far they go -- Claudius already knew the cut-sleeve story, but he has a new appreciation for it. Claudius would gladly cut the sleeve off even this fine a fabric, if Galahad were comfortable on top of it.
