>>90349477>She's too perfect, she has no real issues, she's just Marco's reciprocated crush
Different anon here but I honestly think that Jackie's been presented that way -so far- because it has served the narrative -so far-. She was the perfect ultracool dream girl Marco completely spilled his spaghetti around for very long. Then they went on dates, and surprise she didn't fall for the "dream hottie turns out to be a vapid airhead bitch, plain girl is much nicer and thus wins" cliche.
After that Marco was still a bit nervous to see her, because actually being in her presence was still very new to him and he was worried he'd fuck up, that Jackie would see the real him and that he's not really all that cool and drop him. But then in Just Friends Jackie comforted him, joked a bit, supported him, and they ended up kissing and becoming an official couple.
So now, with the ease and closeness and proximity, Marco isn't nervous around her any more. And now we're also seeing more new sides to her. The "disease-ridden little angels" and the ear and the way she pranked Marco into almost apologizing to the duck, the weird comment about reading her mind, getting goofy over NOT THINKING ABOUT ANYTHING during summer, and finally the bitch did you just -face in the end.
She's the official gf instead of the unreachable dream girl now, and she's finally gonna come down from the pedestal as Marco gets to know her. She's gonna get a personality, and probably some flaws too.
