Here's a question: is the Peter Capaldi Doctor still married to River Song? Do Time Lord marriages last "until death do you part," or is it more of a "until one of you regenerates and ends up with what might be a completely different personality" thing? It would be kind of weird being a Time Lord marrying a Time Lady and then each of you regenerating every couple of decades/centuries into practically a different person. I'd have a hard time believing anyone falling in love with and marrying the Peter Davidson Doctor, for example, being particularly pleased that her husband just regenerated into the Colin Baker Doctor.
