That brings up another good point... Do you think MC will talk to Asterion a bit more about religion? I know they've brushed over it a little bit, but a more in-depth conversation could be pretty cool.
I'm not against the two getting married or the equivalent, but you'd have to present it in the right way. You'd definitely need to mention how society has changed somewhat, and marriage is considered to be more of a loving union between two people than for power (mostly) in this century.
