Zach returns in season seven, shooting Paul at the end of the episode "Down the Block There's a Riot". He first appears as a delivery guy delivering flowers to Bree. Later in the episode, a gun matching the one used to shoot Paul is found on Bree's couch after Zach planted it there. It's revealed that Zach is now addicted to drugs and gambling and has lost his entire fortune on both. Paul and Mike both momentarily put their differences aside to help Zach by placing him in a rehab clinic for treatment.
