Papa Don't Preach, Vid, Torchwood, by fan_eunice and trelkez. From the entry:
So, greensilver and I may sometimes disagree, but there is one thing we stand absolutely united on. And that is our deep and heartfelt concern for Jack and his unplanned pregnancy. We couldn't just leave him an unwed mother like that, now could we? No, we could not.
You really, really, really have not lived until you see Jack telling his papa he's keeping his baby.
