Summary: Ron had always known his decision would bite him back in the ass one day
Warning: Depending on how you interpret it character death.

Ron knew it was a dangerous secret. It was one of the first things you learn in primary school, some things are meant to be told. Secrets like that could wind up getting him killed.
Ron didn't even know why he didn't tell anyone. Maybe it was because of the pleading look in he gave when Ron told him he knew. Perhaps it was the fact that he insisted it wasn't that bad, in fact it had only happened this one time. It could have been the shame on his face when he learned his best friend knew his most guarded secret.
After a long talk with loud words and sharp tongues they came to an agreement. If things got any worse they would tell her and inform an adult. Neither he nor Ron were happy with the arrangement but they knew it was the best they would get out of each other. Not wanting to break his trust Ron kept the secret, not even telling her about it. But now he wasn't waking up, his Uncle was in jail, she was giving Ron the silent treatment for not telling her, and everybody knew.
For those of you who didn't figure it out "He" was Harry and "She" is Hermione.
