Cas waited until Saturday to round up his siblings, because Saturday was the most likely day for everyone to be home. He waited until Chuck had yelled out something about running errands and meeting with his editor and had left. Then he sounded the sibling emergency alarm until they were all gathered in the living room.

"Alright Cassie, what's the emergency?" Lucifer asked. "Some of us have lives to get back to, you know."

"Trolling religious message boards is not a life, Luci," Michael said.

"It is if people pay you to do it."

"Wait, people are PAYING YOU to log onto Christian Mingle and say "Hail Satan" to everyone you match with?"

"You'd be surprised the things people pay good money for, Mikey."

"So what's the problem?" Gabriel asked. "Are you having relationship trouble with Dean or something?" Balthazar and Hannah gasped.

"SAY IT ISN'T SO, CASSIE!" Balthazar begged. Cas rolled his eyes.

"Me and Dean are fine," He insisted. Balthazar and Hannah collapsed onto the couch with relief. "It's just... Dean said something the other day and it got me thinking, and I don't want to risk bringing it up to Dad in case it's a touchy subject-"

"Get to the point," Anna urged.

"Why don't we have a mom?" Cas asked. The room paused.

"I..." Gabriel started, looking ready to kick himself. "I legit forgot some families had mothers."

"That's....actually a really good question," Anna agreed. "I know we had a mom, but..."

"You remember her?" Lucifer questioned. "I didn't think you would, you were so little." Anna shook her head.

"It's just a tiny, fuzzy memory. I vaguely remember her looking down at me with a weird face after I gave her a drawing or something, I don't know, I don't really remember." 

"Well I don't blame you for forgetting," Michael said. "You were only three when it all went down."

"When what went down?" Hannah asked.

"You guys know what happened?" Cas asked at the same time.

"Oh geez," Satan sighed. "Where do we even start-"

"We probably should've planned for this," Michael insisted. "I should've know you guys would have questions eventually. But then again, none of us ever asked Dad about her, so it's not like he ever gave us a guide on what to tell you."

"What's there even to say?" Hannah said. "We don't have a mom, for one reason or another. Knowing what happened doesn't change the fact that she's not here, and if the reason she's not here was important for us to know, then Dad would've mentioned her. But he didn't, so she must not be something he wants to talk about."

"But don't you want to know?" Cas asked. "Aren't you even the least bit curious?" Hannah shrugged.

"Honestly? No."

"Can't say I blame you for that opinion," Balthazar agreed. "If I was in your shoes, Hannah, I'd hate her guts."

"You know about her too?" Cas demanded. Balthazar shrugged.

"Not really. I have some vague memories like Anna does, only a lot more of them, but I was so little that I didn't understand what was going on. One day we had a mom, the next day we didn't. I just remember Dad being angry a lot, and then one day he stopped being mad and started being... Dad."

"Can we quit being vague and actually get the story?" Gabriel asked. 

"Fine," Lucifer sighed. "Mikey, you tell them."

"Why me?" Michael demanded. "You were there too!"

"Yeah, but you're the smarter one, so you probably understood more than I did and can tell it to them in a way that makes sense. I'll chime in when I need to." Michael rolled his eyes.

"Fine..." He sighed and looked at his siblings. "Granted, when most of this went down, Luci and I were barely six, so our memory might not be perfect, but it's the best you're gonna get without asking Dad or Amara." He thought for a moment. "We had a mom. Her name was Naomi. I'm not positive of what her maiden name was, something with an M, I think, but that's not important. And when we were little, and I mean LITTLE- Hannah was only a couple months old MAX- she left, and never came back. The end."

"What do you mean, she left?" Cas asked.

"I mean she left us. She didn't die, she wasn't sick; her and Dad didn't even have the worst marriage in the world. She just up and decided one day that she didn't want to be with us anymore, and so she left. She and Dad got divorced at some point, of course, and she didn't fight for custody. She sends checks in the mail sometimes, probably for child support, but that's it."

"She didn't just not fight for custody," Lucifer added. "I remember. There was one day where they couldn't find a sitter, so we went to the court room with them, and she said she wanted nothing to do with any of us. The judge offered joint custody, which Dad agreed with, and she said no. The judge said that even if she gave full custody to Dad, she could still see us a few times a year, and she said she didn't care. She and Dad fought for the rest of the day after that one, and she was gone the next morning."

Silence settled over the room.

"She didn't want us," Cas finally whispered.

"No." Lucifer confirmed. 

"Are- Are you sure?"

"Very sure. She wasn't a great mother, Cassie. Wasn't horrible, wasn't mean, just... We're better off without her, trust me." Silence again.

"Well....then screw her." Hannah said finally. "She doesn't care about us? Her loss."

"But what if she cares now?" Gabriel said. "We were seven kids under seven back then, who wouldn't want out of that? But maybe now she's had time to really think about it and she might-"

"Might what, Gabe?" Balthazar asked. "Want us back? Randomly come walking through the door? She hasn't made one attempt to contact any of us at all. Why would she suddenly care? Why should we care?"

"We shouldn't," Michael said firmly. "She did absolutely nothing for us, and she never will. We have no reason to care about her. We've had good lives here. Dad takes care of us, he loves us, and he and Aunt Amara have given us everything we could possibly need. We should be grateful to them for all they've done, not hung up on a woman we barely remember that abandoned us."

"No one's saying we're not grateful, Michael," Anna insisted. "We are. It's just... it's not always easy not having a mom, no matter how good to us Dad is."

"I don't see how that's true. We've never even mentioned her until now, and that's only cause Cas brought it up because it only NOW just hit him that 'hey, someone else brought me into existence. What happened to that person?'"

"Just because we didn't bring it up before now doesn't mean some of us haven't been wondering about it," Anna declared. 

"Then why didn't you bring it up earlier?" 

"Because we never talk about her!" Anna insisted. "And I thought..."

"You thought what?"

"I thought she died," Anna said. "That explained it all to me. Why we never mentioned her, why we were so young when she suddenly vanished. I thought something had gone wrong when Hannah was born and she had died, because it didn't make sense to me. It doesn't make sense to me- Cas was only one. Hannah was months old. MONTHS. What kind of person would abandon their family with kids that little? What kind of mother is okay with leaving their infant behind like that?"

"Hey," Hannah said gently. "I turned out okay without her."

"I know you did, but that's not the point."

"It doesn't matter," Lucifer insisted. "She left. Why? We'll never know. Was it a terrible thing for a mother to do? Yes. But it happened, it's done with, and we should let it go because getting worked up about it doesn't do any of us any good. So now you know, and now you can just forget about it, okay?" The rest of his siblings nodded slowly.

"And nobody bring this up to Dad," Michael added. "Naomi is a sore subject for him, I think. It's not worth it."

The sibling meeting disbanded quickly after that, leaving Cas alone once more.

Now he knew why they didn't have a mother, yes.

But now...for some strange reason he couldn't identify, he wished he knew where she lived.

He wished he could talk to her.
