Ryan missed the birth of his second son during treatment, and Mackenzie was clearly overjoyed when he returned home and finally met baby Jagger.
Unfortunately, Ryan was soon back to his old ways.
Less than two months after he left treatment, Ryan was arrested for heroin possession. He also faced charges for skipping out on a bar tab, but those charges have since been dropped.
Ryan has been in jail ever since. He'll remain behind bars at least until his trial begins on April 15.
