And here I was thinking the proposal and marriage would happen in the middle of the assault on Prixima's keep, with Mannan presenting the service while Gregor and Charlotte cut a bloody swath through the troops.
I was thinking of doing something like this (though the third Pirates of the Caribbean movie was in my head, not MGS4

), but I decided to do it this way for two reasons:
One, everyone's going on about this being a suicide mission. Gregor's trying to have confidence, but in Tue back of his mind he's worried. And when you're going on a suicide mission, you don't wait until during the mission to ask the important questions as things could go wrong very quickly. You ask beforehand, so at least you don't have to wonder any more.
Second, more pragmatic/out-of-character/metagamy reason was that I doubted very much that Haspen would upgrade the support rank to S mid-battle :p
