Bryan Cogman, writer and producer on the show, said on twitter they shot a Jon/Ghost scene but it was cut. This isn't the first time an scene featuring Ghost doesn't make it to the show, they deleted an scene with Ghost and Dolorous Edd last season.
FYI... We shot a Jon/Ghost scene. Didn't make it in. I tried! Thx for watching, everybody. #Stormborn— Bryan Cogman (@b_cogman) July 24, 2017
