Two days later, Steve sat beside Emma in the lobby of the airport as they waited for Riley's plane to land. After announcing Emma's current whereabouts, Riley decided to head to Hawaii to help protect his baby sister.

"You okay?" Steve asked as he took Emma's hand in his and linked their fingers together.

"Yeah, I'm fine," she replied with a smile before resting her head against his shoulder. Steve leaned over slightly to press a kiss to the crown of her head.

"Oh, I meant to tell you that Grace has requested your presence at her birthday party this Saturday night," Steve said.

"Well, I will definitely be there," Emma replied with a chuckle.

"There's a catch though," Steve said causing Emma to raise her head to make eye contact with him.

"And what would that be?" she inquired.

"Grace said you have to come as my date," Steve said with a grin on his face. Emma sat still for a moment and let out a breath before replying.

"Well I guess if that's what the birthday girl wants…"

"Hey! You mean you wouldn't go with me if she hadn't requested it?" Steve asked incredulously. Emma burst out in laughter.

"Of course I would have, you big baby," she said with a grin.

As the two of them bantered back and forth, neither of them noticed two sets of eyes watching them interact. One set of eyes held confusion while the other set held anger. But before either of the watchers could react, Emma spotted one of them with a shriek of joy.

"Riley!"

Within seconds, the petite blonde woman had her arms wrapped around and equally blonde albeit taller man. There was no mistaking that these two were siblings. Riley's muscled arms banded around his baby sister as he held her for the first time in nearly two weeks.

"Ah, Emma," he breathed as he caught a hint of a catch in her breathing. "Don't you go crying on me!"

"I missed you," she said as she pulled back slightly to get a good look at her brother's face. She saw happiness and exhaustion etched into his features.

"I missed you too, kiddo," he replied as Steve stepped into his line of sight. "Hey."

"Riley, good to see you," Steve said as he waited for Emma to step aside so he could shake Riley's hand. The tall blonde man pulled Steve into a brotherly hug and they both slapped each other on the back a few times. As Emma watched them embrace, she felt all sorts of strings being pulled on her heart. Here were two of the most important people in her world.

"Any luck with a lead before you headed out here?" Steve asked as the three of them began walking towards the parking lot. Riley slung his military issue duffle bag over his shoulder and walked in between Steve and Emma.

"Well, a couple of the guys had requested time off prior to the announcement, but everyone is being monitored even the guys who call in sick. We'll find him," Riley said for Emma's sake.

"So, how about we introduce Riley to Kamekona's culinary skills?" Emma said as they climbed into Steve's truck. Riley took the front seat while Emma climbed in the backseat behind him.

"Who's Kamekona?" Riley asked as Steve pulled in to the airport traffic.

"One of our friends," Emma said with a smile. "He owns a shop right on the beach."

"Sounds good to me, if you're game," Steve said as he noticed Riley's raised eyebrow at Emma calling Kamekona "our" friend.

"Let's do it," Riley said with a smile directed at his baby sister.

Several hours later, the trio made their way to the McGarrett home. After a much heated debate between Steve and Riley about who would sleep on the couch, they agreed on Riley taking the couch since Steve had to get up early to go to work. After leaving Riley downstairs, Steve and Emma both headed upstairs to get ready for bed in their separate rooms. Emma was just getting comfortable in bed when her door quietly opened and Steve entered before quietly closing the door.

"What are you doing?" she whispered as he climbed into the bed with her.

"I'm sleeping with you. What does it look like?" Steve asked with a grin.

"Riley is downstairs," Emma said as she simply stared at him in shock. Granted, they had not discussed telling Riley about the nature of their relationship, but Emma was pretty sure that Steve would not to cause any problems. To be perfectly honest, she wasn't sure how her brother would react.

"Em, I don't care if your brother knows about us," Steve said as he rested one hand against her cheek. "Do you?"

"No, Steve, I don't care. But, I'm not sure how he's going to take it either," Emma said quietly.

"I'll tell you what," Steve said as he got out of bed. "I'll sleep in my room tonight and then tomorrow I'll tell Riley about us. That way there is not sneaking around or being secretive."

"I like that idea," Emma said with a grin. "One thing before you go."

"What's that?" Steve asked as he watched her shuffle closer to him.

"Kiss me," Emma said before going on her tiptoes. Steve met her halfway with a groan leaving his lips. They allowed themselves a few moments to savor the goodnight kiss before pulling away from each other.

"See you in the morning," Steve said before quietly leaving the room.

Little did either of them know, but across the street the other person who had been watching them at the airport earlier that day was closely watching the McGarrett house as the lights went out. Sitting behind the wheel of a rented SUV, the occupant of the vehicle tightened his gloved fingers around the steering wheel.

"Dammit, Emma! I told you not to bring anyone else into this! Now you're living with a Hawaiian cop. There will be hell to pay, and I can promise you, baby, you will be begging me to kill you before all is said and done."
