I started looking through the "bombing of babylon" tag, keeping an eye out for "brian hurt or down a well" along the way. Do you happen to remember if the fic you're looking for is either *mpreg* or totally AU (B/J don't meet til after bombing)?

Well, I know you said you didn't think it was mpreg, but I did find this previous post where you asked about bombing au fics, and you got rec's teinisydan's mpreg Here By Your Side and loved it.

It does have a scene similar to what was described, B doesn't die, and it's still pretty much canon up to that point because they don't know he's pregnant until after.

Whether this is the one or not, could you update your post? Thanks :)
