Rodney's surprisingly good with children. No one's more surprised than he is. Except for John.
"I hope you picked someone really intelligent, otherwise it seems like it would be kind of a waste. Of incubation time, if nothing else."
By the eighth time John Sheppard married Rodney McKay, they were old pros at the wedding thing, having weathered not only an Ouishan blood wedding, but also a twelve-hour Avalonian handfasting, a Malanese necklace exchange, and a Thurtu joining ceremony that invoked a fire god and featured seven kinds of cake.
Rodney hadn't been expecting the knock at the door just after midnight, answering it with a fractious six-week-old baby in one hand, bottle of warmed milk in the other, and three-year-old Madison wrapped around his left leg.
John Sheppard has always been aware of his responsibility to his parents, his family name, and his daughter. When Rodney McKay moves in next to him and proves to eschew most social rules, John is torn between admiration and fear for his own reputation.
When a run-in with an Ancient machine leaves John ready to bear a child, he has to make a decision that will affect not just him, but the very recent changes in his relationship with Rodney.
Slightly futuristic AU: When Rodney McKay is forced to leave the Mars mission, he finds himself back on Earth and with an uncertain future. With little to lose he picks up a one-night stand who turns out to be pregnant and funny and smart in addition to being hot. John Sheppard has to fight his own demons of the past. In the span of just a few days, Rodney finds in him someone who understands Rodney on so many levels that losing John is soon one of Rodney's greatest fears when he has to face the consequences of his actions.
