After Justin's death, Robin discovers under the table dealings and shady business that Justin was wrapped up in - and is forced to sell most of his and Justin's property in order to pay the overwhelming debts Justin accumulated.
Robin was thought to have been the second of the Executioner's victims, as he was attacked with pair of knives that cut through his wrists. He managed to escape the Executioner and was sent to the Waterbury Hospital with protective detail. However, it's revealed that attacking Robin was a distraction in order to reduce the personnel attending Justin's party - who was the actual target.
