[Locke.]

Jon will never fight Daenerys for the throne. He's not an entitled brat like she is. If she dies then he'll give up his title in the North and take it, but wouldn't otherwise.

Ep6

Spoiler:

After this episode I think it's time for Jon to just remain out of battles tbh. Him and Robb are polar opposites in this sense. Jon makes the smart choices when it comes to alliances and plotting, Robb won every battle he went into and tactically outclassed every battle commander he came up against, including Tywin, Jaime, and the Mountain. I don't think we've actually seen Jon win a battle of his own accord yet
