The charmed timeline has been slightly condensed so it can work that Paige has a six year old.
The Vampire Diaries timeline is ambiguous. Pre-breaking of Klaus' curse.
It had been a long time since Alaric had heard from his childhood sweetheart, Paige Matthews. They grew up going to the same school together and started dating in high school, but then Paige started to struggle when her parents died. She went to college and got pregnant then. Eventually, she moved to San Francisco and Alaric barely got to see the baby. Alaric let Paige pick the first name if his baby got his sir name. Hence, Primrose Holly Saltzman.
So when he got a call from Primrose's uncle (since when did she have an uncle?), Alaric was surprised. Paige and her half sister died in a random attack and though Primrose's uncles and Aunt Piper were more than happy to take care of his baby girl so she could remain with her family (cousins, half-sisters, half-brother, uncles), Paige wanted to give him a chance with the six year old.
Alaric didn't know what to do. He wasn't allowed to have Rosie stay with him before because Paige had hated Isobel in college, but Isobel was dead, and so was Paige. When he told Rosie's Uncle Leo that he would take her, he seemed displeased, but said that one of the brothers-in-law or aunt would bring the girl out after the funeral (he learned Paige married Henry and Patty's widower uncle was Coop).
So, after he got the phone call, he rubbed his face with his hand and headed over to the Gilbert house. He had to talk to Jenna. She didn't know about vampires, but she would notice a small daughter running around.
He knocked and Elena answered the door. She let him in after greetings and he then found Jenna in her bedroom, typing on her bed on her laptop.
"Hey Jen, do you have a minute to talk?" Jenna nodded and Alaric sat across from her. "In a few days, my daughter, Primrose, is going to come stay with me." He held his hand up, asking her to let him finish. "I should have told you earlier, but I never see her, so I didn't think it was relevant. Her mom and aunt died. I was given a choice. I want her. She's six and her mom died. She needs me." Jenna nodded and hugged Alaric.
"You'll do fine, Ric. I can help with anything. You two can stay here if you want."
Alaric nodded. "I'll think about it. She's going to need more space. We can ask Jer and Elena later."
After that, Alaric laid on Jenna's bed as she worked on his computer. "What was she like?" Jenna suddenly asked.
Alaric looked to Jenna. "Paige?" Jenna nodded. "She was so vibrant. And happy. But then her parents were killed in a car crash and she survived. She was never the same for as long as I knew her. She was sadder, darker. You could see it in her eyes."
Jenna didn't know what to say. "I'm sorry. It sounds like you loved her."
Alarics throat got thick, so he nodded. "Listen, I'm going to head to my apartment. I have to make a lesson plan for class on Monday."
Jenna nodded and kissed Alaric in the doorway of the front door. "Call me if you need anything."
Alaric left, but instead of heading to his apartment, he headed to the Mystic Grill. He order a bourbon and sat there, looking at it. It was hard to believe that he would finally get to see Rosie, he always wanted to see his daughter, but he felt terrible this was the way he'd get it. He downed his bourbon and left the Grill. He needed to be alone. So he walked. And walked. By the time he found himself back at his apartment, he walked up, shedding his jeans and climbed into bed. Knowing that he had to prepare for his daughter.
The next morning, Alaric woke up at five to hear his phone blearing.
"Hello?" He answered gruffly.
"Alaric Saltzman? This is Paige's-" his voice faltered over Paige's name "Paige's husband. Henry. Listen. I'd love to keep Primrose, I really wouldn't mind. In fact, I want to keep her for as long as possible. But she is having a breakdown, and Piper is trying to soothe her, but she isn't calming down. We-we were wondering if we could bring her a day or two earlier? Like as soon as she comes down."
"Yeah, yeah, sure. Should-should I come there?"
"No, no. Someone will bring her. It probably won't be me or Coop. We- we need to stay with our kids after wh-what happened. But, Leo or Piper will come. Or both of them. Thank you. I know it seems like we're unloading her on you, but we really love Rosie here. We want her. But we don't want her to suffer."
Alaric reassured, "I know. Paige told me about you. I'm sorry about your losses. I-I lost my wife a few years ago. If you need to talk to someone-" Alaric was caught off by someone (he assumed Primrose) sobbing and yelling.
"Listen, I got to go. We'll come sometime this evening or mid-afternoon."
Henry hung up, leaving an extremely worried Alaric on the other line.
**One hour ago, San Francisco***
Piper was combing her niece's hair. Her baby niece. It seems like just yesterday Paige was moving in with a two year old Rosie. And now her sister was dead. Her thoughts died when a demon shimmered into the room. Piper froze for a moment, but pushed Rosie behind her. The demon hissed at her and Piper went to blow it up, but missed and took out its' arm. The demon threw Piper into a wall and murmured a threat that it would be back.
Rosie looked at her aunt. And screamed. And kept screaming. Her Uncle Coop ran in, looking frantically for a threat. He ran over to Piper and called for her husband. When Leo appeared, Coop approached Rosie. She kept screaming and sobbing. Even when Piper was healed and replaced Coop. She was in so much pain. And she could feel everything.
"It hurts. It all hurts."
Piper looked startled at Rosie's statement, and realized her powers were growing. And she was an empath in a house full of mourners. And Rosie was still struggling. Coop called Henry over, but she kept screaming. Henry left the room, to call Ric, Rosie's father, and explain the situation (in non-magic terms) to him.
Piper was starting to become worried that Rosie would become dehydrated, or something, but Leo came down with an empath-blocking potion. Rosie drank it and stopped. Stopped screaming. Stopped everything. She looked catatonic. Piper picked her niece up and placed her on her lap, as Leo tried to get the girl to recognize them.
Hours later, Leo packed Prim's bag for her and Piper was fussing her niece (freshly out of her cationic stage). The boys were left with their uncles, cousins, and Grandpa Victor.
Leo and Piper orbed to Mystic Falls (they waited the appropriate amount of time a flight would take). Piper picked up her niece and Leo ushered them over to The Mystic Grill, hoping to get Prim to eat anything.
Alaric was setting up the guest rooms in the Gilbert home with Jenna when he got a call, he looked down, and looked at a number he became familiarized with since Paige's death.
"Hello?"
"Hey Alaric-"
"You can call me Ric, if you want. I feel as if we will have a fair amount of contact the next twelve or so years."
"Hey Ric" Piper stressed the nickname. "I just wanted to let you know we made it to town. We didn't know where the house was, so we are in the town circle, at a 'Mystic Grill?'"
"You should have called me to pick you up at the airport, Piper?" She snorted, but Alaric ignored the sound. "I know where that is, can I come pick you up?"
After confirmation, Alaric called out to Jenna that he was going to pick up the group, and left. He got in his car and stopped. In about an hour, he'd have his daughter completely to himself. He'd never had her alone before for an extended amount of time. He was a vampire hunter. How could he keep her safe. Hell, he died twice a week. He was suddenly regretting his situation, when he looked to see Elena knocking on his window.
"Care for some company?" she asked.
Alaric nodded, grateful, and they departed.
"Where's Stefan?" Alaric started to make conversation.
"He and Damon are at the boarding house, I think. How are you feeling about all of this? Don't think I don't recognize your tactics, Saltzman."
Ric sighed. "How will I take care of her when I can hardly take care of myself? There's a reason Paige didn't trust me with her before!" They arrived at the town, and Alaric parked.
"Alaric, you're a great man. You'll protect her the best way you can. And you'll love her. And you'll have our help. And Damon and Stefan. And Bonnie. And Caroline. Paige had a family helping her and so will you. And she left you her daughter. Obviously she trusted you."
Meanwhile, Piper and Leo were talking to Primrose about her powers. "And we'll orb to you anytime you need. But you have to remember not to use your powers in front of anyone. No one knows about us, Halliwells, here. Alright?" Piper coached.
Primrose nodded and played with the soup Piper had ordered for her. "Okay, Auntie Piper."
She was dwarfed, sitting between her Aunt and Uncle. She was small, even for her age, with bouncy strawberry-blonde hair, big green, soulful eyes, button-nose, and pouty lips. She wasn't using it now, but Piper and Leo were all to aware of their niece's ability to wrap anyone around their finger with one flash of her puppy-dog look.
"Look who's here, Rosie. See that man walking over here? That's your dad, Ric." Prim looked at Piper with big eyes, before turning her attention to Alaric, approaching with a young girl. Prim was clutching Piper's hand, tight, Piper didn't notice, though, she was wondering who the hell was the girl walking up to Alaric. She was hardly legal, no way would he be dating her.
"Hello. You must be Piper, and Leo?" Alaric questioned. At their nod, he said, "I'm Alaric Saltzman, obviously... I-I'm sorry to hear about Paige. I-I really...loved her." He paused for a minute. "This is Elena, my girlfriend's niece."
Piper's face softened and said "Nice to meet you Elena. Ric."
Alaric scratched the back of his neck as he and Elena slid into the booth.
"Do you two want anything?" Piper asked.
Alaric and Elena politely turned Piper down and Leo called over the check as Piper spoke quietly to her niece, soothing her with stroking her hair. Alaric took note of how fragile his baby looked.
The group of five walked out, Alaric and Elena being followed by Leo and Piper, who was carrying Rosie, talking to her.
Leo walked ahead, to Alaric and said "We really appreciate you...wanting her. Loving her. She means a lot to us. Rosie's a Halliwell, even if it's not her last name. Piper's worried about her. She took the deaths the hardest, harder then the other kids and Coop and Henry." Alaric nodded for Leo to continue, sensing he needed to talk "Piper barely has left Prim's side. She misses her sister. Did you know Paige had another sister? Prue?" Alaric looked shocked. "She died right before we met Paige. It was hard on Piper. She's determined to hold herself together, to be strong. I'm worried that once Prim is gone, her, not gone, that Piper is going to crumble. The other kids don't know what's really going on, they're so young. Prim's the oldest of her generation." Alaric unlocked his car, Leo in the front, and the girls in the back.
They rode silently to the Gilbert home, the silence only occasionally broken by a question from Prim to Piper.
They got out and Piper told Prim "This is your home. You're gonna live here for now on...with him and Elena."
Prim seemed confused "What about the Manor?"
"That's still your home, and you can come anytime you want. But you'll live her with your dad,for now" Piper explained.
They headed to the door, Rosie placing her head on Piper's shoulder. Piper began to struggle under the continuos weight, and Leo went to take Prim, but Piper shook her head. She was about to leave her niece with virtual strangers. She needed this comfort as much as Prim needed. Leo backed away, as Alaric led them to the couch.
"Do you want anything to drink? Jenna and Jeremy are out getting groceries for dinner. They wanted to make something special for dinner."
Piper shook her head. "That's nice but we need to get going. We can't leave the others with so many kids for so long." She put Rosie on the couch. "Little one, listen. Leo and I have to go back and help Uncle Coop and Uncle Henry and your cousins. You're going to stay her, with your daddy, but anytime you need us, whatever the reason. Call us. or Call for Leo or Coop. We'll come. We love you so much."
Alaric disregarded the confusion he had of Piper's phrasing, but his heart melted when he saw his daughter cling onto his aunt and cry. "I love you Auntie Piper. I love you."
"What, Prim, not gonna give me a hug?"
The little girl flung herself at her Uncle and he held her tight for a minute before letting go abruptly. "Something's wrong." Prim looked alarmed and Piper looked alarmed. "We should get going."
"Please, be careful. Auntie Piper. Don't go."
"Munchkin, we'll call when we get home and tell you how much we all love you."
Leo and Prim knew what Piper really meant, and Prim watched as the last of her known family departed. A few tears leaked out, but she tried to be strong, like her mom.
