Babysitter au the start.
Adam is visiting Lucifer's house to see his neice(stare at Lucifer). He's playing with her in the living room.
Lucifer is in the kitchen on the phone.
Lucifer:Shite!
Adam perks up and shouts out: What's wrong Luci?
Lucifer comes into the living room looking both angry and sad: That was Charlie's usual babysitter, she said she won't be able to come anymore due to some family issues. Fudge, I don't have anyone to watch Charlie after school, and I work late tomorrow and the rest of next week. I can ask my siblings, but their schedules are as busy as mine.
Charlie puffs up her cheeks: I'm not a baby.
Adam registers what he says, then shouts out without thinking: I can watch Char-Char!
Lucifer looks at him with shock: Are you sure? Aren't you in your last year of college? I don't want you to volunteer just because I'm in a bad spot.
Adam: No, it's great. Really, I will get to see and spend more time with Charlie(and you). Plus, the job market is looking like shit with my schedule this semester. I got all morning classes this year. So watch the twerp, do homework, and get some cash(see you) it will be fucking fantastic.
Lucifer: I'm glad you seem excited to take this on. But, as I keep telling you, don't curse in front of Charlie.
Charlie with a smile on her face and hands on her hips : Yeah, Uncle Addy, no-no words is a no.
Adam: You're right, sorry. So, how much are you paying out, Mr. Employer?
Lucifer: I guess I'll pay you the same amount as Barbie.. since you'll be taking over her Charlie sitting services. Is $20 an hour okay? I can do higher.
Adam: That's more than fucking minimum wage! Hell yeah, it's more than okay! It's a fucking deal!
Lucifer: Adam!
Charlie: Ooh, Uncle Addy is in trouble again.
(I'll have more time to respond now due to being on vacation...so you can ask/message me about this au if you want. I will probably make some doodles, too!)
