We have no affirmative evidence due to the lack of a Robb POV , but I certainly believe he has . I mean has anyone found it odd that a 15 year old boy with zero experience was a tactical genius on the battlefield ? 1 How did the king ever take the Tooth ? Ser Perwyn Frey asked Martyn Rivers . That ' s a hard strong keep , and it commands the hill road . He never took it . He slipped around it in the night . It ' s said the direwolf showed him the way , that Grey Wind of his . The beast sniffed out a goat track that wound down a defile and up along beneath a ridge , a crooked and stony way , yet wide enough for men riding single file . The Lannisters in their watchtowers got not so much a glimpse of them . I believe Robb warged into Grey Wind while he was hunting and realized the trail would be useful . 2 Now he ' s sitting and looking at maps . I asked what he was looking for , but he never answered . I don ' t even think he ever heard me . He wouldn ' t change out of his clothes . They were damp all day , and bloody . We ' ve seen what Bran is like when he is in Summer ' s skin . I believe Robb wasn ' t ignoring her intentionally , but was in Grey Wind ' s skin looking for a way to avoid relying on the Freys .
