Frankie does not complete the task
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Frankie greets Alex, upon entering the room, but not by name. When he reads the task brief out, he skips Alex's name, and points out that he doesn't think he'd already said it when he came in. When Alex notes that he'd hoped Frankie would have greeted him by name, Frankie observes that he obviously hadn't bargained on "Scottish rudeness". He proceeds to unwind the ball of string by rolling it across the room, and gathering the thread in loose bundles in his hands. He then switches to winding the string around one of his hands, and then leaves the resulting messy pile of string on the desk before saying Alex's name and starting to leave the room. When Alex checks with him that he's done everything on the task, he re-reads the text on the front of the page and decides that he has. He never finds the additional text on the back of the task brief, and therefore does not complete the task. In the studio, Frankie argues that "You can't just hide bits of the task", and suggests that it would not stand up in court. Greg offers to financially back Frankie's lawsuit against Alex for hiding part of the task brief from him. Alex confirms that Frankie's timer for the task was still running, after 172 days, so he places last in the task.
