So I saw this and thought this would fit Blake and Jaune perfectly!
"Hello, girls~!" Jaune Arc, master of the arcane and knower of the secrets of the universe greeted with a falsetto tone accompanied by a glittery wave.
"Hello, Jaune." Blake said numbly, as she always had when greeting those who came to her door, even the ones who weren't erroneous. "What brings you here?"
"What, can't a neighbor drop in for a hello?"
"Normally, no, and the case is the same for you because you only visit when you want something."
"Oh, heh heh, I, uh, guess you know me too well, huh, Blake?"
"Uncle Jaune~!" Two children cheered, one with a white cat tail and the other with a short black bob-cut, and jumped into the arms of the large man at the door.
"Salt! Pepper!" He hugged the twins. "How are my favorite, little spices~?"
"I'm not a spice, I'm a mineral!" Salt shouted with defiant glee.
"Oh, somebody's been paying attention in class!" He turned to Pepper. "And how are you? Is your aura still blue?"
"It's actually yellow today." Pepper answered with as monotone a voice as Mother Belladonna. "Is Uncle Jaune staying for dinner?"
"He's probably busy today."
"Oh, so very, very busy. There's a kingdom in need of your Uncle Jaune, and it wouldn't do for a wizard to be late, you know."
"I thought a wizard was never late, nor early." Weiss said with a smirk.
"Mm... True." He chuckled. "Unless, of course, you're Duke Schnee."
"Grandpa?" The twins asked, looking to each other.
"And what does he want?"
"Don't know, but he says he needs a wizard, so I'm gonna go on a little business trip to figure things out."
"And you want us to housesit for you." Blake concluded.
"Heh heh, uh, yeah... That's not too much, is it?"
Blake gave a sigh, taking her children into her arms. "Salt and Pepper have school and Weiss and I need to run the shop." Jaune gave a sad, puppy-dog pout, making Blake smile. She didn't like puppies, or dogs, or happy puppy-dog adjacent things. And Jaune knew that, which is why he knew she couldn't say no to him. "I'm sure I can make some time to check on things."
"Oh, thank you, thank you, thank you so much, Blake! You have no idea how much this means to me! Now, remember, Pyrrha needs to be in before sunset and Juniper needs to be out-"
"After sunrise. I know the drill. Will you stay for dinner?" This time, Blake used Jaune's weakness, which was his god-children's pleading eyes. Such soft, sad, wet orbs of blue and yellow; how could he possibly say no to them?! He gave a sigh and she a smirk. "I'll take that as a yes?"
"I suppose I could stay for a side dish or two." He entered the home, tagged along by the two Belladonna-Schnee children.
Weiss leaned into her lover. "That was very sweet of you."
"He knows I can't say no and I know he can't either."
"Well, regardless, I'm still glad you said yes because I have a question for him."
"Oh?" Blake quirked her brow.
"What spell did he cast to get... those?" The 'those' Weiss gestured towards were the flesh mounds barely covered by Jaune's glittering robe. As he laughed at the children's antics, his fabric stretched to the brink with each sudden rise and fall but never breaking loose by some magical means. Weiss gave a pout of envy. "Because there is no way those are natural."
