"Are you guys decorating the Core?" Addison asked as she walked in to see Harry and Cisco arguing over the tree. "What have you two done with the Harry I know and love?" she joked.

Harry shook his head, "I am merely trying to make sure Ramon does this correctly. Have you told anyone our news?" he changed the subject, stepping away from the tree.

Addy grinned as the others entered the room, as if Harry's comment summoned them there. She lifted her left hand to reveal the ring Harry made for her, "Harry and I got engaged," she shared, her voice much more high pitched then she'd expected it to be.

The room filled with messages of congratulations before Harry wrapped his arm around her waist. "Thank you everyone," Harry replied to all the kindness and warmth in the room, "If you'll excuse me, I have a plan to outsmart Devoe," he changed the subject, placing a kiss on the top of Addy's head and walked out of the Core.

Cisco glanced at Addison, "Do you have any idea what that was about?"

Addison shook her head, "If I knew, you'd be the first to know, but this mission is something he's keeping from me too."

She didn't bother following him to see what he was up to and instead redid the Christmas tree the two men had so wonderfully messed up.

Harry walked into the Core, hours later, just as Addy finished her work to reveal a lump on his forehead. "What happened to you?" Addison asked as she grabbed an ice pack, placing it on his head to help with the pain.

"After I got my project working," he began, "I went to check on Snow because we made her feel like we like Killer Frost better earlier. We were attacked by her meta boss and she knocked me out," he explained.

Addison removed the ice pack just long enough to place a small kiss on his injury, "Poor baby," she replied, "Did Caitlin make it out?" Harry nodded allowing Addy to ask her next question. "So, what was the other project you worked on today?" she asked, curiously.

Harry sighed, thinking over whether or not to share his work, "I created a thinking cap like the one Devoe used. It's our only option to finally outsmart him and get ahead of his plans. It worked," he shared, proudly.

Addy cocked her head to the side, "Can it hurt you? I'm all for beating Devoe but not at the risk of my fiance," she stated, worry in her voice.

Harry shook his head, "As long as I use it moderately, I should be perfectly fine. Just think of it as my sacrifice for the team."

She laughed, tending to his injury once again, "If you're ok then I'm ok, too."

Later that night, Harry and Addison met up with everyone else at Joe's home. Joe had been apologizing for the house not being decorated, but when they arrived Ralph had done it all and he was dressed as Santa.

"This puts me in the Christmas spirit," Addy smiled, leaning into Harry, who was also happily looking on to this group.

Joe walked in after the others to see the Christmas miracle, "Dibny, you did this?" he asked, in surprise.

Ralph nodded, "Don't make a big deal about it. I was just trying to do the right thing."

Joe walked over to thank him while Cisco, in record time, broke out the egg nog, "Who wants un on this?"

Addy's hand went straight in the air as she walked over and took a glass, taking a long swig ready for a refill. Cisco raised a brow as he poured her a second glass.

"Someone brought their 'D' game," Cisco quipped, "D is for Dranks."

Addy laughed, "I knew that," she shook her head and turned to Harry, "Do you want some?"

Harry waved off the offer, "At the rate you're going, I'm going to need to remain very sober to take care of you," he joked causing her to frown.
Harry moved to take a seat with Addison quickly following and resting on his lap, "Do you remember our first Christmas together at STAR Labs?" she reminisced.

He thought back to the first time they had decided to be a couple and grinned as he replied, "I do. Last year just wasn't the same without you there," he admitted.

Addison nodded, "Neither was mine," she kissed him, more deeply then anyone was prepared for before she pulled back, "Let's never spend Christmas apart again, deal?"

"I promise," Harry replied, holding onto her, his arms tight on her body.
