Also, I forgot where in the text they mention this but Arya is described as looking like Lyanna. Elsewhere in the books Jon is mentioned as looking like Arya. so...Jon looks like Lyanna (perhaps his real mother)
Yup, it's the long horse face
I also remember in the first book part of the reason Catelyn despised Jon so much was because he looked more like he would be Ned's child than either Sansa or Robb according to her.
