(( Another crime Theon Greyjoy must be held accounted for. But Davos kept his silence. He wants to know what happened at Winterfell, and reminding him the crime of butchering innocent children will not help. He expect Theon knows that as well, judging by the relief he sees when he recognizes which Stark boy. ))

Then you must know that it was Ramsay Snow that burned Winterfell and blamed it on you as you were taken as a captive at the Dreadfort.

(( To be flayed. But it appears Theon doesn't know that is about to happen. And Davos just doesn't have a heart to tell a man that, even for someone as guilty as Theon Greyjoy. ))
