What is the relationship between Marinette and Pollen, Adrien and Plagg and Chloe and Tikki
Marinette adores Pollen and treats her mostly like a friend and sometimes like a precious pet(?) I can't think of another way to describe it, like, not like a pet as in a dumb animal to take care of but like how you become devoted to your cat or dog and pamper them a little excessively. She's a Bee Mom now.
Pollen thinks the sun shines out of Marinette's face. She thinks highly of most all of her holders regardless of how they use the bee, so Marinette being respectful and justice oriented and creative and willing to listen to Pollen and willing to DOTE on Pollen makes her like level 9000 peak holder. It makes Pollen want to be selfish and hold onto her.
Adrien and Plagg are basically bros. Brothers? Like how you get on each other's nerves but you love each other (and younger Bro Adrien looks up to Plagg a bit for being so "I do what I want"). Adrien wants Plagg's attention and affection even though it's usually irritating, like sharing his cheese or using his hair as a cat bed, but he secretly loves it. It's also nice to have someone constantly next to him willing to throw shade back and forth, not treating him like a tool or hot commodity.
Plagg is so not used to someone as SENSITIVE as Adrien, but while he's bringing out some of Adrien's snark, Adrien's bringing out some of Plagg's softness. I mean, c'mon, he SANG for Adrien, if that's not LOVE-
Chloe and Tikki are basically sisters. Like how you're forced to live together but you have nothing in common but you can't escape each other because you share a room. And Chloe is not having Big Sis Tikki's unsolicited advice. If Chloe didn't need Tikki, she'd probably be locked in a glass case or something or thrown out on the street (which at this point Tikki might prefer).
Poor Tikki is just trying to stop Chloe from ruining everything but it's like Chloe's DETERMINED or something. Dammit, if she didn't have this Older Sibling Obligation to try and make things go smoothly, she'd be so OUT of here. Chloe might be the most difficult holder she's ever had - even if she was stuck with someone like Hawkmoth, at least she'd know where she stood, but being with Chloe is like some weird mid point limbo of "are we doing good? I THINK this is good, but it feels bad."
