No, Emma and Josh look alike, that was even mentioned in the novel. She even told Chase that her name is Baily.^^ But Chase is not the sharpest it seems.
Only in Josh's imagination, everyone else claims that Pete looks like a Josh's mini-me. In the novel it's only the hair that looks more like Chase's.
The “you get with anybody” plot is so unnecessary, I can’t take it serious because there’s no way you look at them and don’t see how they look EXACTLY alike. Just seems like filler to make unnecessary misunderstandings.
