Hearts (chapter 4)

The next few years were strange for John. He and Molly had been going steady since that first week of secondary school, and he and Sherlock had remained friends (as much as Sherlock could have friends), but their friendship was strained. Sherlock would at times treat John the way he had since John was in fifth year, but would occasionally ignore him completely and at other times would be highly protective and possessive of John and try his hardest to keep him away from Molly. John was completely confused by Sherlock’s behaviour, and his life was made even more difficult when his sister Harry tried to flirt with Molly then brought home another girl the next week, when John’s parents went through a nasty divorce, and when Sherlock called John once to tell him in a disgusted voice that Mycroft had begun seeing one of their classmates, Greg Lestrade, and his parents were horrified.
