Can I Scy on Molly's Grave?

Caduceus asks if he could have a one-on-one conversation with Molly Mark. Chester says it's not possible, because we haven't who the dead are. The pair scry on Cree first and then Mollynock's grave before going to Molly's. "I couldn't help but over here, you're talking about scrying," Caduceus tells them as their blood vials rattle.
