This is a stupid argument but you cannot know that line is parallel with the camera. Daft comment. What you can see is how someone has arms and shoulders (Jones) are in front of Rodwell I.E Father Ted Farther away.
feck off, man, he's not gonna look three inches taller than he is just because he's stood perhaps four inches closer to the camera than Rodwell! FFS. He's quite clearly matching Rodwell for height and a couple of inches taller than 6ft Mancienne; if you can't see that from the picture then you're fecking blind and there's no point in anyone trying to tell you any different.
