Well, personally, I believe there is more to his friendship with Mueller than just a bromance. Watching the show, you can see how they act with each other and certain glances they give each other.
Even the girls talk about it and they are a lot less bashful than we are.
During the prep for his 18th birthday party, he said he wanted no girls there AT ALL. He talks about Mueller than any of his girlfriends combined.
All the years I've watched the show, all his girlfriend have been quite unattractive and surprisingly overweight. Which in my view, is a big sign.
But nevermind that--on to more pictures!
