Remus would talk about this idea with Frank and Alice, especially if the couples decide to have more children, and who knows, there would be more additions to their pack.
He would wait until an appropriate time so they could grieve over the loss of their lover. He wouldn't know what to do if he lost Sirius, James or even their son.
"I'll be back." Remus told Sirius and James he went to the Floo system, grabbed some Floo powder, threw it in the fire, and grabbed some more "Longbottom Residence." He came out the other side of the Longbottoms ancestral home.
Alice Longbottom saw Remus and smiled, but she was worried about whether anything had happened to Sirius, James, or Harry. "Remus." She greeted the wolf, not that she cared about that little fact; Frank and Fabian and all knew none cared as he was safe and was always surrounded by his friends, kept away from everyone on the Full Moon.
"Hello, Alice." Remus greeted the witch, the godmother to his baby Harry, as Lily was Neville's godmother. "I came to speak to you and Frank," Remus told the witch, who was quite confused. Remus Lupin sounded so mysterious because he said Alice hated mysteries.
"I wasn't a Ravenclaw for a reason, Remus, so kindly say it straight." Alice told the werewolf he dared to give her a small smile as he did while they were in school.
"As you wish, Alice. I want to invite you, Frank Neville and any other child you might have into my pack." Remus said, stunned Alice. She didn't know what the wolf would say, so she smiled at him.
"Thank you, Remus; we would love to join your pack." Alice said she was pretty happy that the wolf had asked them as she researched werewolves after she found out; she'd tell Frank later about this, and he wouldn't mind as he liked the other triad.
"Thank you, Alice; I'll go enjoy the rest of your day now as I've got to go back to see what James and Harry are up to." Remus said with such fondness that Alice thought the two boys needed play dates. Also, she needed some adult interaction while Frank was working. She loved Neville, but he was not the world's most terrific conversationalist. She doesn't think Harry would be a great conversationalist for James, so that would be good for him, too.
Remus emerges from the Floo in Potter Manor to see a naked Harry running past him while James is after him. Harry has been refusing to wear clothes during the day, especially at night before bed. Pyjamas were easy, but getting dressed for the day was a challenge. "Get back here, Harry!" James yelled out, not noticing Remus either, not that their son had seen him.
"No." Came the reply from the one-year-old, giggling and running away from James. James looked like this was not funny, and Remus didn't find it amusing either. How long has this been going on? He'd play up on his dad when he and Sirius were not around.
"Harry James Potter-Black-Lupin! You put your clothes on right now!" Remus yelled out, making sure the one-year-old could hear him and he could hear James' sigh of relief when he came home. "Do not think of saying no to me, young man." He added that he wanted extra measure, knowing his son would probably say no or why.
"Why Moony?" Harry asked Merlin's sake, and child Remus thought it was either no or why they needed him to speak other words instead of those two and babbling. He walks to see James, who is very frustrated, and Harry, who is still very naked.
"Because I said for you to put clothes on," Remus told the toddler, who pouted and tried to use his cute baby charms on Remus. The werewolf would generally do what Harry wanted. James caved easier than him, even Padfoot did, but not this time.
Harry pouted at Moony. He did not want to wear clothes as they were icky; Harry hated icky things, and he wanted to be a nude boy forever. When he was not going to get his way, he went over to his daddy, pouting as he got dressed while sulking.
"Enough with the sulking Harry just because Moony said to put clothes on." his daddy told him; why could his daddy not understand that he didn't want the clothes on his body? Nobody came here but them anyway. He didn't like the way Moony talked to him, and Moony had never done that to him before.
"No." Harry sulking Little Harry wanted to sulk. He didn't like clothes at all, nor did he want to wear them. Why did his parents not understand that? And he did not like his Moony talking to him like that, and Moony was supposed to be the best one who always fed him chocolate!
"My poor baby." James said, and yes, Harry was his baby for now, but James was getting to the point where he realised that Harry was becoming a big boy. He couldn't let himself keep babying Harry anymore, and it would lead to more problems in the future.
"Harry, a baby." The toddler said he was happy to be babied, even though Moony constantly told him he was a big boy now; his daddy told him he was a baby. Now, James sees why his son was content with being a baby.
"Not when Daddy has a baby." James told the one-year-old, who pouted again, but that did not stop James. "When Daddy, Paddy and Moony have a baby, Harry will be a big boy and brother." James explained that Harry still pouted at this, but he did want Daddy to have a baby.
"I see he is now clothed." Remus said, checking how James would put their firstborn into clothes. The throuple hoped it was just a phase that kids go through and Harry would grow out of it. "How long has this been going on for James?" Remus asked James, the omega of the group, and James looked at his alpha nervously. How should he tell him?
