Am I the only one who thinks that "Danny and I are going to be fine" is a reference to a baby Danny back at home, which is why Clara can't travel with the Doctor anymore? she wanted to tell Danny she loved him and come clean because she was going to announce that she was pregnant, and then he died. There has to be a baby Danny because it's the only way that future descendant pioneer time-traveller Danny can exist, since he a) is a genetic descendent of Clara and b) Looks like Danny.
So, I'm calling it: Baby at home with Clara.
