Ooohhh KNOCKED UP but like, right before the reboot would actually happen so when they come back she's like, just finding out she's preggers and he's all OMG WHAT?!
Or, he knocks her up just as they're returning in reboot mode. Like, they're on and off for hookups cuddles but don't stay "together" because they have to save face for their teams so they hook up with others but always go back to each other and then he knocks her up.
