Einar identifies the wrong Olli
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Einar very quickly guesses, in under 10 seconds, that the real Olli is the one on the bench. As he leaves, he asks if he is done, and all of the Ollis nod in response. It is at this point that he appears to notice that there were more Ollis in the garden than he had initially spotted. For being wrong but fast, he earns third place.
