I want a scenario where Adrien finds out his scarf was actually from Marinette and not his dad, and for it not to go very well at first.
Because while I’m sure Adrien would understand it was a mix up and still, his friend went out of her way to make him a gift, I can’t imagine him really looking at the scarf for a while and being happy about it, not while knowing his dad didn’t actually get him anything at all. Adrien would have very mixed feelings about it IMO, and I wouldn’t really blame him either.
So, angst time. Adrien wants to confront his dad about it but he’s overseeing a fashion show and he couldn’t ask Nathalie because she went with him, so that leaves Marinette. He pulls her aside after school, and there’s so much anger and resentment for his dad building up, and he really doesn’t want to take it all out on Marinette, but Adrien’s afraid that if he opens his mouth he might say something he’ll come to regret, so instead he pulls his scarf out from his bag and smooths out a corner of it, displaying Marinette’s tiny signature for her to see.
He can see the panic flash in her eyes while she stares at the scarf, but it doesn’t seem like she can find words, so he asks a question, “Why didn’t you you say something?”
Meanwhile, Marinette really IS panicking. True to what she told Alya all those months ago, Marinette tries to explain that she didn’t want him to be disappointed that the scarf wasn’t actually from his dad, just her, but even as she explains this she can see it’s not making Adrien feel better and honestly, it’s no wonder.
(“I wish you said something earlier,” Adrien finally says, and he’s rubbing his neck and chuckling and trying to keep the situation light. “I feel like a bit of an idiot.)
Because Marinette let the secret go on for too long, and surely finding out a cherished present wasn’t actually from his dad after all this time believing that it was… it must have hurt. It must have hurt ten times worse than if Marinette would have just told him the truth, though surely that would make her look like an opportunist more than anything. She didn’t want to come off as selfishly wanting his attention. Marinette was stuck, honestly. She didn’t know if there was a right way to have gone about that situation. So she says the only thing she can.
And offers the only thing she can think of.
“I-I can take the scarf back, if you want.”
Now Adrien feels bad, because he really wants to keep it. He wants to look at the scarf and think, ‘my friend made this for me, she took time and care to knit this with me in mind.’ But instead, all he can see is Gabriel Agreste’s stern face, and all he can think when he sees the baby blue fabric is that his own dad didn’t even bother buying one of those lame pens for his birthday this time.
Tentatively, he hands the scarf back to her.
