She's about to caveat that that Lancelot will explain it better, but honestly she's not certain that's true. He'd been ever so out of it. Instead, she says, "I'm afraid I don't have all the details. I know Lancelot found Magnus and removed the sword and tried to stop the bleeding until Magnus could heal himself. I know he took the sword and the glass to Lan Wangji, lest it disappear. I know it was unclear to him, what happened before he arrived. He looked a frightful sight when he came to me. He realized Magnus asked for you when his stress response started to recede." Susan never apologizes unless she's truly sorry about something. Now she says, "I believe I owe you an apology. I might've found you myself, but Lancelot was feverish and falling asleep when he realized, and I stayed with him."
