John is like alot more hyper and very American and he's really OTT.
Edward is the more serious and laid back one that looks like he would be abit cheeky to you in real life.
If you remember the clip from last night when they were talking about breathing the same air - Edward just sat in bed agreeing and John was the one talking about how amazing it was breathing air.
I think John is the one putting the shampoo and conditioner on and Edward is the one that looks like he's about to go nuts and punch someone because he's only up.
