13 Reasons Why Season 2: 10 Big Questions We're Left With

In addition to sleeping with Jessica, Justin is harbouring another secret: he's still using heroin.

Justin has made one bad decision after another, but he's had zero parental figures in his life to point him in the right direction. His mother is more interested in doing drugs than looking out for his wellbeing, so it's no surprise that the teenager found himself homeless in Season 2.

With Clay's mom and dad formally adopting Justin into their family, the troubled teen finally has something to lose. Will he break the habit of a lifetime and give up the drugs, or will his heroin usage be his downfall?
