Kono had a plan for her teammates. She believed that Steve and Danny needed a bit of a push to get together, and Christmas was the perfect time to do the pushing. She had the perfect weapon: mistletoe.
After hanging the mistletoe at the entrance to the bullpen, she watched and waited, after ensuring that her cousin Chin was aware of its presence.
Before long, Kono was rewarded by the appearance of her boss and his partner. As usual, the two men were arguing.
"All I'm saying is, you drive all the time," Danny said as he and Steve walked in. "Every time I get in the car with you I feel like I'm taking my life in my hands. I'd really like to live long enough to see my daughter graduate from high school. Besides, it's MY car!"
"Have we ever had an accident, Danno?" Steve asked as they walked. "No, we haven't."
"Now you're answering your own questions," Danny grumbled.
They stopped in the doorway. "I know this island better than you do. That's all," Steve continued. "Wait a minute. What's that?"
"What's what?" Danny asked.
"I felt something brush against the top of my head. Oh."
"Oh what, tall guy?"
Steve looked up. "It appears to be mistletoe." He broke into a broad grin.
"Oh no you don't. Seriously. You're not going to...." Danny protested.
"Come on, Danno. Where's your Christmas spirit?" Steve leaned down and kissed his partner.
Danny's protests died away, to be replaced by appreciative noises as Steve kissed him. Danny's arms were soon wrapped around Steve's neck as he returned the kisses.
Watching from a few feet away, Kono turned to her cousin. "It worked," she said.
"Yeah, but it looks like those two are going to be busy for awhile. I don't think any of us are going to get any work done," Chin Ho complained.
"It's almost Christmas. Who works on Christmas? Come on, I'll buy you a Longboard," Kono answered. "Bye, guys!" she called over her shoulder.
"Mele Kalikimaka," Chin added as he and Kono left.
The two men kissing under the mistletoe ignored them.
