A Common Misconception:
After the scene where Billy beats up Steve (which I do not condone btw I just think it may be able to be forgiven), I saw a lot of posts arise along the lines of 'why do you ship them? They hate each other!!!' I wanted to clarify something:
Billy does NOT hate Steve. Billy was angry, fed up and stressed about what his father would do to him.
Billy appears amused and even heavily fond (*cough* in love with *cough*) of Steve for almost all his scenes. God, look at this and how amused/fond (aroused) he looks:
Now, something that is less explicit.
Steve's feelings for Billy.
It would be obvious to assume that after the fight, he would hate Billy. And he might.
But he didn't always.
Gosh, he even looks like he kinda likes him, (if he's not a little irritated by his arrogance) especially in gifs like the one above.
So, yeah; hi, Billy and Steve didn't hate each other (or at least, not until after the fight)
(Also who looks at their "enemy" like this?)
