ceiling, she makes the mistake of putting her drill on in reverse. But in the end, she gets her first passing grade. Hanging Mirrors The nominees are to install four IKEA KRABB mirrors on a wall, in any configuration they choose. Darryl – The ongoing arguments between Darryl and Sara persist throughout the challenge, which Andrew sees as adversely affecting Darryl's performance. Dr. Hill suggests that Sara should tackle a challenge alone if this persistent negative behaviour continues. Sara finishes the challenge without Darryl's help, but no footage of Sara's work was shown. Merle – Merle is shown levelling his mirrors as he is installing them, which, to this point, he has eyeballed. Despite his newfound meticulousness, he only manages to finish three mirrors. Keith – No footage is shown of Keith's work, but he finishes hanging all four mirrors after 75 minutes; however, he uses an extra screw to keep the mirrors in place. Barry – No footage is shown of Barry's work, but he gives up after hanging three mirrors. Jeannie – Jeannie initially misinterprets the pictorial instructions of marking the wall with a pencil with nailing the hanging bracket in place with pencils as nails. She does, however, finish two mirrors. Screwing a Hook The final challenge for the nominees is to hang a hook from their patched ceiling so that a plant can be supported on it, then spend the rest of the afternoon redoing and/or completing whatever previous tasks were unfinished (including decorating their apartment) for their final apartment inspections. Darryl – After attaching his hook, Darryl focuses on getting his newly redesigned shelves into place. Darryl's ceiling patch is the only one to fail to hold the weight of the plant. Merle – Not wanting to be named the worst after cutting himself during the Upholstery Challenge, Merle is determined to get this right. After attaching the hook, Merle proceeds to tear down and redo his leaky plumbing (during this time, the fourth mirror was also shown completed). Despite his incomplete plaster job (necessitated from having to redo his patch), the hook holds the weight of the plant. Keith – No footage of Keith's work is shown, although Keith's hook does hold the weight of the plant. Barry – Barry's mural has been completely redone, with a blue coat covering the bottom half of his wall. His hook holds the weight of the plant.
