#i don't ship them but i do think that clizzy is what happens when people take the “other girls” “me” cartoons and make them kiss

What I think works so well about Clary and Isabelle's friendship is that they're very similar people, but they present themselves just differently enough to appear alien to each other. Both of them were the only girls in a group of boys (Isabelle was raised more or less isolated with Alec and Jace, while Clary doesn't seem to have any friends other than Simon and to a lesser extent his band), and they responded to this in very different ways. Isabelle basically committed herself to her role of "the girl" and always performs extreme femininity, while Clary attempts to sink into the background as "one of the guys." Both of these behaviors can be seen as rebellions against their culture. Isabelle comes from the very misogynist world of Shadowhunters, where women are respected as warriors but expected to act in a masculine way in order to earn that respect. She rejects this, and proves her place as a brilliant fighter while maintaining her fun and glossy feminine traits (compare her with Jessamine Lovelace, who was seen as silly and frivolous for her feminine interests). Clary on the other hand is a child of the nineties growing up in NYC. As a teenage girl in the early 2000s, she would have been surrounded by "not like other girls" philosophy, and hyperfemininity would be both pushed on her and demonized in popular culture. Because of all the pressure placed on gender roles and her lack of connection with other girls her age, it's no surprise that Clary would develop a certain bitterness towards people who perform gender in a way she won't.

With all of that out of the way, we get two teenage girls who have no fucking clue how to handle each other. They're both jealous of how the other one fits in with the guys in a way they can't. Obviously any friend group is made up of friendships which fit together in unique ways, but Clary and Isabelle both see themselves as The Girl, and thus are worried that the other one will make them redundant (Clary gets along with Jace, so will he still need Isabelle? Isabelle and Simon are getting along, will this take away Clary's place as Simon's most important person?) Of course this isn't something that will actually ruin their friendships, but Clary and Isabelle don't know that. Instead they need to learn how to engage with each other, and I enjoy that TMI actually shows them having those conversations. They're trying, but it doesn't all happen at once. Clary still has bitter thoughts about Isabelle's femininity, and she also looks down on other girls like Maia.

Speaking of Maia, there's a really good moment in COA where Clary starts grumbling to herself about how unfair it is that a werewolf can be pretty, and that Maia should be gross and hairy. She then catches herself, and literally thinks "this is exactly why I don't have any female friends," showing that thanks to Isabelle she's learning to recognize her internalized misogyny. She can hang out with other pretty girls, and it doesn't decrease her value as a person.

It's just so nice seeing a character whose internalized misogyny is actively acknowledged by the narrative and treated as a flaw she must overcome. So many female protagonists in the early 2000s (and other decades) had the hyper-femme "best friend" who they hated, but even though that's how Clary sees Izzy at first, she's able to look past it and see the ways they click together. The two of them don't become besties immediately, but they're at least able to get past that first layer of hostility.
