John and Sherlock get murdered or are as good as dead anyway (maybe John is comatose with little to no chances to be back again and Sherlock gets into a mental hospital with no chances to recover). What's more tragic is that they've left their little son or daughter behind (an AU where Sherlock is a rare type of boys who can give birth, so it didn't take long for John to get him pregnant).
The child is an orphan now (or as good as orphaned, depending on what happened to his or her parents). Greg and Mycroft are distraught because of what happened to John and Sherlock. They can't just leave the child, so they decide to adopt him or her.
Bonus if the child is very difficult at first and refuses to understand that his or her real parents are gone (even if they are physically alive, which is even harder for him/her to understand).
Please, a lot of tears and angst, but I'd love John and Sherlock's child to get used to his or her adoptive parents and love them (never forgetting whose son/daughter he/she really is).
John/Sherlock, Greg/Mycroft. Possible char. deaths. Greg and Mycroft adopt the orphaned child. Angst
