In Never Back Down, I don't understand the relationship between Max Cooperman and Ryan McCarthy.  At the beginning of the film scene they appear to be on good terms   Ryan is observing the fight Jake interrupts Max and Ryan are very friendly at the party   However later in the film he becomes friends with Jake and the rivalry develops   He sees (and presumably knows) Ryan beat up Jake in the bathroom He's aware of the rivalry and Ryan's determination He knows of the friction with Baja/Ryan/Jake   Knowing this why would he agree to join Ryan at his house (leading to his hospitalisation)? It he being naive or is this simply being used to tell the story?
Are Max Cooperman and Ryan McCarthy friends in Never Back Down?

We already know that Captain America is the first avenger.  There is a Thor in the avengers team and he is older than Captain America. Why do we call Captain America the first avenger?
Why do we say that Captain America is the first avenger?

Rachel absolutely hates living in Joey and Chandler's apartment after losing the game and bet to them.  REFRESHER The bet was if Monica and Rachel lost the game, then Chandler and Joey move into Monica and Rachel's apartment.   She says she hates the color, hates how it smells like birds, and how its a "guys apartment".   HOWEVER... When she later moves in with Joey due to Monica and Chandler getting together, the apartment is in even worse condition than it was when she was previously living there with the well known neat freak Monica.  It just didn't make too much sense to me, and I know that this is just a nitpick, and it could just be an oversight of the writers and crew, due to how many episodes were made.

Why does Rachel hate living at the other apartment?
