Chez/Claret friendship or Bradley/Claret friendship?
Okay, this is a toughie. Claret loves them both a whole lot, and it's like you're asking me if I love Batman or Ironman more. (Please don't do that to me, I will cut all your fucking children. Kay, love you.) Good thing I'm not close friends with either of them (lone wolf, y'see) otherwise this would be fucking hard for me, too. Now to go all devil's advocate on this shit.
Chez and Claret are like brother and sister. They even refer to each other that way. He's really terrified of her, too. So, I'd say they're like Johnny and Sue Storm. Chez is Johnny; talented, flambouyant, vain, and cocky - and he'll occasionally get in over his head with his competitiveness and need to strut his stuff. Whereas Claret is more grounded, level-headed and they both know she wears the pants int his friendship. They entertain each other, and look out for each other. (Except Claret does it indiscriminately of gender. It's okay, kids. It's not Barder's fault he's afraid of girls). Also you'd need to understand that Hall is apparently also his friend, so I guess he couldn't go all Me Tarzan, You Dead on her. That being said, Johnny would do pretty much anything for Sue. I'm rambling here, look at their faces instead.
Aren't they adorable? Awe - I think I have a cavity now, fuck it.
Moving onward. Sir Bradley James Harris, and Claret. Ha, okay, so it's obvious why they'd be friends. Same house, both charming pricks, both have great hair, both are close (whether in a positive or negative way) to Guac and Chez. The reasons go on for miles. Their friendship was fairly unproblematic until Bradley's flavour of the week (and literally just a week, fuck) Eleanor Jane Hall decided that starting fights with your boyfriend's friends is a wise idea. Okay, this is Petra's job, so I'm not going to go too deep into it, but no. Just never do that. If you were my girlfriend, that would turn me off so fast, which is a shame because you're pretty gorgeous. It seems Bradley didn't let the word poison going 'round about Clary affect his opinion on her, which is noble and charming. Great props to you. I think they're great friends. Now, look at their faces as well.
But let's face it kids. Even if I did decide on the curly monster of epic adorableness, Chez would pop up and axe me worse than Deadpool would. Not a nice death, not a nice death at all.
So, I guess that decides it.
The winner of this round is
May the force be with you.
