Fancy: So, your mother said you were very excited last night. Did something special happen?
 
Crescent: ….
 
Fancy: Sweetie? [Notices her head bobbing and smiles] Sweetie, did you doze off again?
 
Crescent: [Head snaps up] Huh! N-no, of course not! [wipes drool from chin]
 
Fancy: [Chuckles] Whatever you say, sweet heart.
 
Crescent: What were you saying before?
 
Fancy: I was asking why you were so excited yesterday. We don’t often see you so chipper after class. Did something good happen?
 
Crescent: [slight blush] W-well, I was hanging out with somepony… a stallion.
 
Fancy: [Flinch] A stallion you say?
 
Crescent: Dad, don’t get all puritanical on me. We discussed this, didn’t we? I’m old enough to hang out with stallions.
 
Fancy: And yet you can’t brush your own mane?
 
Crescent: [pout] It’s not like I can’t! It’s just… I like it when you do it. It feels nice to have you watch over me like this.
 
Fancy: [dad smile] You are buttering me but I’ll let it slide just this once.
 
Crescent: How magnanimous of you, father-dearest. Speaking of moods, you and Auntie seemed pretty upset yesterday. Did something happen?
 
Fancy: [Freeze] …Sweetie, what do you know about your mother?
 
Crescent: [Frowns] My mother?
 
Fancy: The one who gave birth to you. That one?
 
Crescent: [Scowls] Oh, her… I never met her. I know she ditched me and left me my one gift from her. [presses hoof to the scar on her neck] Why do ask?
 
Fancy: [Looks over to the drawer where a letter resided. Within was a note from Crescents mother.] Would you ever want to… meet her?
 
Crescent: Tartarus no! She made her feelings about me abundantly clear when she dumped me on the streets and tried to kill me! I don’t ever want or need to see her!
 
Fancy: [Flinches] I-I see… [Thinks to himself but is torn]
 
Crescent: [Sees her dads ears droop and sighs] Besides, I don’t need to go anywhere see my mom. My mom is right downstairs, burning pancakes with my Aunt and brother. [She nuzzles her father] I have me dad right here, so I don’t need to go looking from some other ‘family’.
 
Fancy: you know you’ll always be my little lemon pie, right?
 
Crescent: [blushes] D-dad, don’t call me that! I’m not a filly anymore!
 

 
I finally chose a hubby for Rarity, yay!!! Anyway, Fancy and Crescent spend few hours together (since both are constantly busy wit other things.) but the one thing they always share is mornings. Every morning, Fancy Pants brushes Crescent’s mane, styling it in such a way that always makes her happy. He used to be terrible at it, constantly hitting her ears or tugging at the knots that accumulated as she slept. After years of practice, he can now do her mane without causing her pain.
 
It took months for Fancy to gain enough of Crescent’s trust and he loves that she can now relax enough to fall asleep as he does her mane. Plus, its the only time she doesn’t wear a choker or scarf while indoors.
 
Note: Crescent’s mane is super curly, so it’s constantly getting tangled, hence why she sometimes uses it to hold her stuff. It’s nothing like Pinkie’s mane but it can hold quite a lot.
