Are Jon and Dany gonna have a very modern conversation?

1. we know Jon is terrified of fathering a bastard.
2. Dany just told him she cannot have children: "they are my kids, they are the only children I am ever gonna have. do you understand?"
3. #boatsecks
4. HEAVY pregnancy foreshadowing. so, with all this, will there be a "will you marry me?" followed by "are you only marrying me because I am pregnant?"

and, realistically, will there be time for a wedding? or will Jon in fact father a bastard? or will it just be a small ceremony performed by Sam?
