Later as Lucy was asleep and 707 went home Mammon was sitting in the kitchen with Lucifer to talk things out.

Lucifer : I didn't mean what I said.....i never wanted you to leave......"

Mammon : I couldn't face you anymore. I thought i thought it was best.....I .....I know I shouldn't have and I'm I did.....I never wanted this to mess things us n-

Lucifer : that doesn't matter anymore it never did......I was still dealing with things.....maybe I wasn't over it like I thought. But I shouldn't have taken it out on you"

Mammon : how......how has he been?"

Lucifer : .......he misses you never stopped looking for you"

Mammon : ......honestly I don't think I ever would have returned to devildom .........not after everything that happened......I couldn't bring Lucy there and risk them hurting her"

Lucifer : I don't think that would have been a problem but I understand your fears"

Mammon: what do You mean?"

Lucifer: few times and more recently they tried instigating things with him to start something and once they mentioned you.....what they did to you. Barbatos could barely keep him back. Since then they haven't been seen causing trouble"

Mammon : ......"

Lucifer : how are dealing with it all?"

Mammon : ....... I can't have Lucy think I'm wrak......I have to be strong for her......but not a day goes by where I don't think about it........my powers still haven't returned fully I'm still injured.....it's almost like I'm human......

But I've been seeing someone about it but making sure to leave certain things out. MC was right this therapy thing helps."

Lucifer : .....so you named her after me I presume?"

Mammon : heh.....yeah.....you're still my brother......you're important to me so I did name her after you.....she's a sweet kid.....most of the time"

Lucifer: why keep that thing around?"

Mammon: 707 isn't that b.....he's not that much of the worst he's been helping me raise Lucy.....which I think was a horrible decision on my part because now she's talking about world domination and tried making a cult at kindergarten and convincingthem to give her their lunch money......but I'm kinda proud on that she's like a little con artist"

Lucifer : and good at it unlike you"

Mammon : .....true....."

Lucifer : he says you work alot?"

Mammon : I do.....I have to .....the human world really sucks"

Lucifer  : are you busy or the weekend?"

Mammon  : no why?"

Lucifer: would you like to spend time with us?"

Mammon : yeah Lucy would like that. I talk about you guys all the time with her...."

Lucifer  : does she know what you both are?"

Mammon : no....she thinks we're just human like everyone else.....eventually I'll tell her.....but that might fuel her cult thing....."

Lucifer : eventually she'll grow out of the cult faze like satan"

Mammon : I don't want you to be mad at Asmo he was just trying to help. I can't imagine felt great hiding this"

Lucifer  : I have no right to be angry after everything I said"

Few days later Mammon arrived somewhere with Lucy and they then walked over to everyone.

Lucy: these are my uncles and aunt?"

Mammon  : yeah"

Lucy: are we demons?"
Mammon p: i....how did you know?"

Lucy : 707 and me were spying and said everyone's names were demon names and the way everyone talked sounded like you were demon's so are we?"

Mammon: .....yes we are"

Lucy : ok 707 said he'll keep it a secret he pinky promise me"

Mammon: I'm not worried not sure anyone would believe him"

Lucy  : who's Diavolo?"

Mammon  : i....he's your father"

Lucy  : ......how was I made then?"

Asmo  : i-

Satan  : shut up"

Asmo : ........"

Mammon  : i.....umm magic?"

Lucy : why isn't he around?"

Mammon : i....ummm....i-

Lucifer  : well your father is prince of devildom where we are from so he's very busy"

Lucy : will I ever see him?"

Mammon: yeah soon....."

Lucy : so I three dads?"

Mammon : y-wait what!?"

Lucy : you 707 and Diavolo?"

Mammon : h...he's not he's just your nanny"

Lucy : why can't he be?"

Mammon : .....that's not really how things work.."

Lucy : why?"

Mammon : I......someone help...."

Nobody knew how to respond to what Lucy asked so everyone just brush off the question and went on with their day.
