Magnus nods, expression resolute. That's okay. Presumably Hanguang-jun only asked the essential questions -- Magnus knows they're not close. Certainly if he asked if Shen Yuan had a message for anyone, he'd definitely include Magnus in that list, so it's fine. Magnus has been talking to Shen Yuan's future body when he's alone with it, just sharing all of his fears and hopes and other feelings; Shen Yuan can answer when his spirit is inside of it. That's enough. "It's okay. He told you what array you need?"
