Ask Ausellio - 14th Feb Spoiler (Spoilers)
I wouldn't say C has been a great friend to D, but he did have mediocre sex with an asst editor to help D find out his book being published. Also, he stopped him from making a fool of himself at B's engagement party and took care of him that night when he was wasted. And yes, you are correct that D helped C too.
Chuck bought drugs and hookers for Dan. Also, Chuck took a wasted Dan home and tucked him in instead of let him lie in the street. That's making him a good friend since this is the very same he does for Nate and they're besties for years now.
Well ok he has been a friend but not a great one and like i said before chuck would of been dead ages ago if he did not help him. remember the pain addiction?
So fucking excited to see this.
