Well now she's having a sneaking suspicion of just when this Gabriel is from, though admittedly she isn't very clear on how he went about running away from his war. Maybe he did simply spend a lot of time on Earth long before that happened, maybe she's misinterpreting his hesitation talking about heaven and his earlier reaction to a mention of his brother. She's rather hoping that's the case.

"But you haven't left heaven permanently?", she asks as neutrally as possible. If that's yet to come for him, she definitely doesn't want to have to tell him, even if he's going to forget about it when he wakes up.
