Summary: Holmes and Irene are thrown for a loop when the United States government decides that Irene Adler being in the United States is too much of a security risk. The decision to deport her back to London is expedited for the fact that Irene is pregnant with twins, and the government does not want her children born on US soil. Holmes decides to move back to London to be with her and their children, and they are once again surprised that evening, this time by by Joan's decision to move there as well, partly to start a new career as a pathologist at St. Bart's alongside Molly and partly to be closer to her long distance boyfriend.

But complications ensue when, upon her arrival in London and in the presence of Sherlock and John, Irene goes into labor. Despite their best efforts, there is no way for Holmes to arrive in time for the birth of his children, leaving his cousin to be there in his stead. Sherlock gets four broken fingers and an end to his fight with his girlfriend Molly as a result, and when Holmes finally does arrive later in the evening he gets a most welcome surprise.
Author’s Notes: Part of my "The Family Business" series (found here on AO3). Please read the authors notes at the post because there's about six fics that are supposed to take place before this one that I wasn't able to write in time, and there's a summary of those fics in the authors notes. Those fics will be written on Tuesday or Wednesday and I'll hit you with them all at once, so apologies in advance. I hate real life sometimes...
