What do आप think would have happened if Jon left the दीवार and joined up with Robb and his army?

I think it's hard to predict because so many different things could happen! First of all I think Robb would be shocked since he believed Jon had left for the wall! सेकंड I'm certain Catelyn wouldn't like it at all! But I don't think द्वारा any chance that Robb would execute Jon without question! Robb is too loyal for that! He would ignore the rules if his brother came to fight द्वारा his side!

Robb and Catelyn would also have quarrels whether it's right या wrong
