Some time after the truth about Ozpin was revealed to Jaune.
He went drinking.
Now, normally he would ask Pyrrha to accompany him when he goes drinking, to ensure he doesn't get married. Again.
But.
She's dead.
Since she died, he hasn't had a drink.
This not drinking, was one of the main reason he was mad at Qrow. Lazy bastard didn't share.
His friends tried to stop him, not that hard though, since they understood why he was drinking, but his sister didn't like the idea of him underage drinking.
He got drunk anyways.
And woke up with a ring on his finger.
By now he knew what to expect. So, he rolled over to see his lover-for-the-week, as he liked to call it, since a week was the longest it took him to get a divorce.
He saw blond hair... And a hand with two wedding rings.
Oh.
