A couple of days later, Aaron was in the kitchen making a light lunch when his son Jack came in to the room. He looked at his dad in his sling and working one handed and he asked, "Daddy where's Papa?"
"He needed to take a nap so he's sleeping little man." Hotch replied as he spooned some mac 'n' cheese into two bowls.
"Are you and Papa going to get married like you and mommy were?"
"Why do you ask that Jack?"
"Because Papa's been around for a really, really long time but you don't wear rings or anything. At school most of the mommies and daddies wear rings and have the same names as us kids."
Aaron thought for a minute and then asked, "So you'd want Papa's name to be Spencer Reid-Hotchner…."
Jack interrupted and said, "You forgot the doctor. He's a doctor Daddy."
"So Dr. Spencer Reid-Hotchner? You want him to have our last name?"
"And I want his too if he's gonna be here with you."
"I'll think about it." Aaron said as he put spoons into the cooling bowls.
As Jack sat at the table he said, "And you need Papa's name too."
Aaron grinned and said, "I'll think about that too and I'll talk to Papa about all of this."
"Cool." Jack grinned.
That night while Aaron and Spencer were getting ready for bed Aaron said, "Jack was talking to me at lunch today and he had a good point."
Spencer propped himself up on his side and he asked, "What was he talking about?"
"He was talking about us getting married."
"Married?"
"Jack wants your name to be, and he emphasized the doctor part of your title," Aaron grinned and continued, "But he said he wants your name to be Dr. Spencer Reid-Hotchner."
"He wants me to take your name?" Spencer asked curiously.
"And he wants us to take your name. He wants us to be a family in all of it's sense."
"I know we've been together for a long time but are we sure?"
"Spencer, we've been together for five years, seven months, two weeks, and three days. I'm sure of this. I just didn't know where Jack stood with us possibly taking that step in our relationship."
"What about our jobs?"
"Our jobs are fine and if they don't work out then we can teach or whatever we want to do."
"Should we just take Jack to Vegas or have our team around for the ceremony?" Spencer asked going into planning mode.
"The team would kill us if they weren't there but no more talking tonight. We'll figure this out and go from there." Aaron pulled Spencer down for a kiss and Spencer returned it.
"I love you Mr. Reid-Hotchner." Spencer giggled.
Aaron groaned and said, "You'll be Reid-Hotchner too and so will Jack."
Spencer kissed the tip of Aaron's nose and said, "I guess we'll have news to tell the team tomorrow or should we wait and send them invitations."
"Invitations are good. Let them be surprised." Aaron said as he rolled his hips against Spencer's own arousal.
Two weeks later, Spencer helped Aaron up to the BAU. Aaron was still in the sling but the dressings were basic gauze pads and instructions to work on his range of motion. He came in with his jacket over his shoulders and Spencer close enough he could smell the soap he used. He could get very used to this and when Spencer went to go to his own desk Aaron leaned in close and said, "Thank you Spencer."
The team just grinned at how the two were acting and Rossi said from the top of the stairs, "Just kiss him Aaron so we can get to work."
Spencer bit his lip and Aaron grinned at the suggestion. He pressed his lips to Spencer's forehead and said against his skin, "We'll have to take longer lunches I think."
Spencer couldn't help the smile or the laugh and said, "We need to get to work." He pulled away from Aaron gently and Aaron nodded before he headed up to his office. Things were definitely about to get interesting around the BAU.
