JJ hadn't slept well the night before, she was nervous about how the Will's and Henry's meeting would go the next day. Henry was super excited. He even tidied up all his toys, which were usually lying across his bedroom, and sometimes the living room floor, without JJ having to ask him. The whole team now knew Will was Henry's father, a mystery they hadn't been able to work out since JJ announced her pregnancy. She was going to keep it between Emily and herself until the time came but after the team got a case on Friday afternoon she decided to tell Hotch to see if she could stay behind because Henry was meeting his father. Hotch was understanding but wasn't sure on it, but JJ explained that this would most probably stop her from not needing to stay behind as often. So Hotch agreed. Having the media liaison there for all cases from here on was worth her missing this one now. After their meeting JJ decided that she should just tell everyone. All were shocked at the discovery but not all that surprised-they weren't sure how but they could tell that JJ and Will weren't just old work acquaintances.

Henry was so eager that from getting home, from the morning in the park, he would look out the window whenever he heard a car. After about ten times of saying 'he doesn't finish work until 3.30pm' JJ just gave up and laughed. And from three thirty he didn't take his eyes of the window. JJ was glad Henry semi knew what his dad looked like otherwise every other second would have been 'is that him?'

Will and JJ had only talked one other time during the week. Will called to see if he needed to bring anything but JJ said they would just be staying in, as the weather didn't have the best forecast for the afternoon. There had been a few texts making sure it was still going ahead, but other than that JJ had wanted to give Will some space.

At ten to four Henry's smile and eyes widen to fill his face, and JJ could tell that meant only one thing. Henry ran to the door and JJ followed a little after knowing it would take Will a couple more minutes to get up to the apartment. Henry was bouncing with excitement as he heard the door knock. JJ looked through the peep hole even though she knew who it was. Suddenly Henry became nervous and hid behind his mother's legs. She couldn't help but laugh, he hadn't done that in so long.

"What are you doing?" JJ asked amused.

"Nothing," Henry replied shyly still holding onto her jeans.

JJ smiled and shook her head as she opened the door. She knew she didn't need to talk to him, because within a minute he would be back to his regular bouncy and jumpy self.

"Hi, how was work?" JJ asked stepping aside to let Will in, Henry following behind her.

"Dragged on. A lot of paper work" Will answered smiling down at the boy hiding behind his mother. Truthfully it only felt like it dragged on because he had so wanted to get here and kept looking at the clock every five or so minutes.

JJ nodded knowing exactly how that felt. JJ looked down at Henry and gave him an encouraging smile before closing the door, but Henry didn't let go of her leg. "Sorry," JJ mouthed to Will.

Will decided to just go for it, he bent down to Henry's level and held his hand out to take. "Hi Henry, I'm Will."

Henry took a step away from his mother and took Will's hand. "That's my middle name," Henry said in response as he came out of his sudden shell.

"Really?" Will asked smile at his son and then looked at JJ with an inquisitive smirk.

"Well, it's actually William," JJ said biting her lip shyly to Will.

"Yeah, but you said that about Will in my class."

"It's a nickname, like sometimes I call you 'Hen', because it's a shortened version of your name, and not because you're a female chicken," JJ replied looking down to her son.

"Then it's almost my middle name," Henry said looking back at Will.

"It's a good name," Will replied not being able to hide his grin.

"Henry would you like to lead Will in to the living room?" JJ asked, thinking they probably didn't want to stay in the hallway all afternoon.

"Okay, I can show you my trucks, they're really cool."

"I bet they are," Will said walking alongside JJ as they followed their son to the living room. "So, William?" Will grinned.

"Well you are his father, and seeing as you're a 'junior', I guessed it was a family name," JJ answered. She wanted Henry to have some tie to his father, even if he didn't know it. Plus at the time of his birth JJ was still planning to possibly call Will.

"It is, thank you," Will had always wanted his son to be a 'William' as well, but not after himself, but as a memory to his father, so the fact that he was, made Will all the more pleased. Additionally it showed JJ was really thinking about Will at the time like she had said she'd been.

"Okay, well I'll leave you two to it," JJ said as they reached the living room. Henry was already sitting on the floor getting his trucks out. JJ and Henry had discussed how today would go. She would leave Henry and Will alone in the living room while she watched on from the kitchen. She thought that was best for father/son bonding, especially when the father part and her were still on the somewhat outs. She also had brought a lot of files home with her as a make up for not going on the case. Though it wasn't like Hotch would know how much she would and would not have done.

"Woah, are these all yours?" Will asked sitting down on the carpet next to his son.

"I have more in my room, but they don't get along," Henry said, and Will just nodded along guessing it was a story he had made up.

"Which one's your favorite?" Will asked.

"This one," Henry said reaching across the toys and holding it up to show him proudly.

"Why's that?"

"It's red."

"Is that your favorite color?"

"Uh ha, and it makes it go faster," Henry said moving it through the air quickly. "Which is your favorite?" Henry asked.

"Well I don't know if I have a favorite yet, but this one looks cool," Will said picking one up in front of him. "It reminds me of one my granddaddy had when I was younger, we got to ride in it when he visited."

"Yeah that one I like a lot too," Henry said.

"I like this one as well," Will added picking another one up. "We drive these at work a lot."

"Really? That's cool! Mom said 'you're a policeman'."

"Yeah, I'm a detective."

"Is that like what Mom does? Cause she said you met while working."

"Kind of, just your Mom's jobs a lot harder than mine," Will answered and Henry nodded along.

"I want to catch bad guys when I grow up," Henry said moving his toy across the carpet.

"It's a lot of work", Will said and Henry looked up. "But you'll be good at it," Will winked. "And my Daddy was a Detective too, so it's in your genes," Will said with a large smile on his face, and Henry had one of equal size.

…

"Where's the bathroom?" Will asked Henry while they were playing. Will wasn't sure how long he'd been there, it hadn't felt long, but he was so eager to leave the precinct that he'd forgotten the last time he went to the toilet.

"It's over there," Henry said pointing passed his mother.

"Thanks, I'll be back," Will said though he didn't know exactly where Henry was pointing, but he walked towards JJ anyway.

"It's straight through," JJ said pointing through the door behind her as she had overheard Will's question and Henry's lack of answer.

"Thanks," Will said walking in that direction.

Henry ran over to his mother, while Will was in the bathroom. "I like him," he whispered.

"I'm glad," JJ replied, giving him a side hug and kissing him on the forehead. "So you're having fun?"

"Yeah," he nodded. "He knows way more than you do about cars and trucks."

"I bet he does," JJ laughed. "Why were you so shy when he got here?" she asked.

"I don't know," Henry answered honestly. He didn't know why he had hidden behind his mother's legs, it just happened.

"But you're okay now?" JJ asked and Henry nodded with a smile. "Good. So you're okay with seeing him more?"

"Yeah," he said nodding faster than before.

"He'll be so happy to hear that."

"What do I call him?" Henry asked.

"Sweetie you can call him whatever you want. 'Will' or 'Dad' or-" JJ started but couldn't think of a third option. "He'll like either."

"Okay," Henry answered. But after hearing the toilet flush he ran back into the living room and sat back down.

"He likes you," JJ said when Will walked passed.

"I like him."

…

"Do you guys need anything?" JJ asked coming into lounge and checking in on the boys. Will had already been there at least two hours and after working almost nonstop for it, she thought a break was well deserved.

"Juice, please," Henry said happily.

"I'm fine, thank you," Will answered.

"Are you sure? I'm making coffee anyway."

"Uhhh," Will said giving JJ a weird look, but she knew what it meant.

"I'll make it weak just for you," JJ answered rolling her eyes.

"Okay then. Yeah sounds good," he smiled, he had an early morning, so a Cup of Joe would do nicely right about now.

JJ walked off shaking her head as she went, Will hadn't changed. A while later JJ came in carrying two mugs in her hands and a juice box between her arm and her chest. She handed the mug to Will before handing Henry his juice.

"Thank you," Henry said taking the straw off the side of the box.

"Woo," Will said taking a sip.

"Seriously?" JJ asked. "You're a light weight,"

"No you're just super human. What is your stomach made of? Iron?"

"Almost seven years and you're still using the 'it's gonna burn a hole in your stomach' joke?"

"What can I say-once a classic, always a classic."

"Did you want me to get you some more sugar or milk?"

"Nah I'm fine," he said taking another sip and putting it on the coffee table.

"Mom can Dad stay for dinner?" Henry asked, and Will was overjoyed by the name he was just given. He hadn't expected that. JJ was glad Henry had settled on the better option of the two. Truthfully it would have been strange to hear 'Will' come out of her son's mouth. But neither she nor Will, wanted to push it on him, they both thought it was his decision to make.

"I have no problem with that. I was just going to order a pizza," JJ said to Will.

"Then I'd love to stay," Will answered.
