meantime, has gotten all six doors mounted but is making a fourth attempt at making them all balanced and close together. When Keith wants to partner with Darryl again, Darryl advises him to start the wallpaper, a bad decision considering that the drywall must be done first and that Keith had failed miserably in his drywall challenge in Episode 4. Keith starts incorrectly again as he chooses to start wallpapering next to the door frame in the middle of the wall. Andrew convinces Keith that the wallpapering is incorrect, which only makes him take his 17th break of the day. As Andrew is trying to press Keith back to work, he learns that Keith has made a wager with Rob MacDonald, the show's own lighting technician, with McDonald betting ten dollars that the wallpapering would not be finished before time ran out. Andrew also accepts the bet (surprising Merle, who had also taken a break and was in on the conversation), believing that he's in for an easy $10 (he's later proven right when Keith ultimately gives up with a half-hour remaining). When Keith returns, he begins in the corner without taking down his first piece. His next piece isn't lined up at the seam, nor is his piece cut to get around the door frame. Because the wallpaper was started before the drywall, the strapping for the drywall is in the way and Keith is attempting to address this by removing the strapping, which he gives up after about a minute. His alternative method of working around the strapping is far worse, as it leaves a gap between the strips of wallpaper. Andrew convinces him that the wallpaper should be taken down and the drywall be attempted first. Meanwhile, Merle has completed the frame for the glass block window. Without the frame, the port is designed to hold five blocks per row with a reasonable gap. However, with the frame in place, only four blocks can be accommodated per row, resulting in leftover blocks. To address this, Merle accepts Barry's suggestion of making the space between the blocks wider, claiming that the frame space at the Grand Hotel, where the nominees are staying during rehab, is wide. Merle, Darryl and Keith mix the adhesive (or rather, Darryl and Keith watch as Merle does the mixing). Merle makes the perfect mix, but Darryl's laying of the adhesive between the blocks
