Oh! Hummmm. I'd be willing to change things up so Lamont did both, but she's actually for sure breaking cover. She does the dumb hero thing and rushes out when it's clear her Servant is in danger and ends up, like, cradling his body while he's dying. So I think that will not work. :(

That said, I can at least provide this: Xion can teleport, so she can break cover without giving away Lamont's location if you prefer!
