And so Emma was there and something happened where either her foster father or one of their friends had hurt her in the past and Emma either went their to confront them or something along those lines and Emma either beat the guy up or damaged some property.
Let’s assume that’s really what happened. If Henry’s father really did have something to do with her going to prison, maybe he’s the one who suggested that she go and confront the person who hurt her? (Assuming the father is Bae, suggesting that someone stand up for themselves would be something the Bae we all know would definitely support.)
