A/N: Hello Everyone, this story is a sequel to The Hawaii Sunscreen Algorithm. It was a journey into my folly, and I plan to bring you back there with this one. For this story I am introducing the characters from NCIS: Los Angeles into the mix, but as before this is going to focus on Hawaii Five-O and The Big Bang Theory. If you haven't read The Hawaii Sunscreen Algorithm, you might want to pick up on some of the little references, but if you aren't so inclined, I hope you enjoy my folly once again.

To those of you who have read the Algorithm and who told me that I had to send the Five-Os to California, this story is for you. I wasn't going to write a sequel but because so many of you messaged and commented that I should, I am. Thank you for being loyal followers of mine, and I hope you love this interaction between of favorite superheroes and our favorite super geeks.

Chapter 1: I'm Going, Going Down to Cali, Cali

Steve McGarrett sat drumming a pen on his desk protector, watching the rain fall increasingly more violently on his office window. God forbid he'd be bored. Five-O had so many cases they could take over from HPD, but Steve was kind of in a mood to be bored. It had been quite a while since he'd gone anywhere exciting, and even through he loved Hawaii and had been pretty badly injured in North Korea, he was pining to find intrigue in a new place.

During his time with the SEALs he'd been many, many places; never staying in the same one for very long. Japan had been all about work. Korea had been all about helping Jenna. Both places had proved to be huge disappointments. Steve wanted adventure, he wanted to see something different for a little while, wanted to go away but most of all he wanted an adventure and he wanted to take all his friends with him. After hearing about, but not getting much information into the case, Steve felt a little jealous of Chin and Danny, for having ventured off the island and to California for a case, but at the same time, he didn't regret what he had done to put Wo Fat behind bars.

As Steve sat, getting antsy by the moment, while his crew seemed busy enough out in the common area without him, his eyes wandered to the photographs that had found their way into his office. Grace's picture along with a rather crazy one of Danny, Chin and Kono at the beach were placed on one of the book shelves, but the one that had really caught his eye was one that was taken when he had made some of the most unlikely friends he'd ever had.

The photo had been taken at a comic book convention held on the island in which four Californian scientists made it their mission to make Steve and Danny, and their whole crew, into Superheroes. The photo was of Steve and Danny, complete with Batman and Superman t-shirts, with their new friends Sheldon Cooper and Leonard Hofstadter, who had decided to dress up like Danny and Steve, complete with badges and bullet proof vests. Steve chuckled to himself remembering the whole Hawaii adventure that was had by the Californians and desired an adventure like that to happen once again.

It had been quite some time since Steve had heard from the gang back on the mainland. Sheldon had Skyped a few times, but life, cases, everything that Steve was not finding interest in at the moment had happened, and they had not spoken in almost a year.

Steve's phone rang in that moment, his office phone, and as he glanced at it he picked it up.

"Hey Sheldon, I was just thinking about you!" Steve stated as he had caught a glimpse at the Pasadena area code.

"Um…Steve McGarrett…?" the male voice asked but it wasn't Sheldon.

"This is Steve McGarrett." Steve stated and looked at the number again.

"Sam Hanna," Sam stated, "When am I gonna get that steak dinner you owe Me." he asked with a laugh.

"Come to Hawaii and I'll buy that for you!" Steve snickered to himself.

"I was already in Hawaii, named the Camaro, and caught one of our guys hiding out on your island. Where were you?" Sam asked.

"Top secret mission," Steve stated trying to be vague, "oh, and Danny didn't like the name you picked for the Camaro, but he renamed it when he got back from California."

"Was the top secret mission the one involving you crashing a plane that was carrying Wo Fat on it?" Sam asked, "I'm NCIS, my friend, nothing is top secret from us."

"I should have known," Steve sighed.

"We know you caught the guy, so good on you," Sam stated.

"So did you call just to get me to buy you the most expensive steak you can find, or is there a problem officer?" Steve asked mockingly.

"Actually, it's a courtesy call," Sam stated, "What can you tell me about Frank Delano."

"He dropped off our radar, but he's wanted on multiple charges here in Hawaii." Steve stated as he sat up, his boredom disappearing. "Unfortunately because of my other endeavors, I can't tell you as much as some of the people on my crew could."

"You wouldn't want to pack up the crew and come and lend us a hand back here on the Mainland, would you, because your boy Frank has killed three navy officers and is ransoming two more for information on you." Sam asked indirectly.

"Why does Frank want information on me?" Steve asked suspiciously.

"That's what we have to find out; preferably before Frank kills anymore naval officers." Sam answered.

"Alright, we're on our way." Steve stated and hung up the phone.

"Alright ladies and gentlemen, today marks the beginning of our two week count down to Comic Con!" Doctor Sheldon Cooper stated once he had all of the member of his social group gathered in one space. "This is going to be a big year for all of us, and we're coming off a really great year of previous comic book conventions, so good work all of you, but Comic Con is the big one, the grand daddy of them all, and we can't be wasting our time. Leonard, give us a rundown!" he ordered.

"Friday, Saturday and Sunday in San Diego, with big panels, twice as many venders and cosplay giants from around the world," Leonard stated, "people, this isn't a joke."

"Howard, who are we dying to see?" Sheldon asked as he paced before the gathering.

"Doctor Who's panel looks to be the high light, with Once Upon a Time, keeping a close second, but as always, Star Trek has a discussion and fan appreciation every day of the convention. Once again, Leonard Nimoy and William Shatner will be in attendance and with our new friendship status with Will Wheaton, we are on the ins, for the Next Generation panel and VIP walk." Howard explained.

"You realize I'm going for the shopping right?" Penny stated.

"We expect you to," Sheldon retorted, "we can't have any distractions Penny, so we expect you to be as far away from the convention as possible all three days. The only reason we're taking you is because Bernadette, as one of the group by marriage, is going to need entertaining. Amy, you're onboard for the same reasons."

"Understood," Amy stated as she nodded. "But I do want to go to the Once Upon a Time panel."

"Here, here," Penny and Bernadette echoed.

"We are so happy that you three have found a good, quality show to get behind." Sheldon smiled, "but again, we can't have you as distractions so you will be on your own for the panel and anything you do afterward at the convention."

"We're going to the panel, gonna oogle the pretty men like prince charming and then we're leaving," Penny stated un-amused by Sheldon's tone.

"Do you think he's gotten worse since he met the super SEAL?" Amy asked as she leaned in toward Leonard.

"Absolutely, he thinks his got experience as a navy commander now and it's driving me crazy!" Leonard whispered.

"Now, let's talk cosplay people!" Sheldon stated and turned around one of his dry erase boards. "This year we have to come up with something spectacular for the fandom parades, but as always I think we should stick to what we know."

"Too bad no one in California knows who Five-O is. Those were some of your best costumes yet." Bernadette stated reminiscently.

"Affirmative, Bernadette, but irrelevant for this convention," Sheldon stated.

"Do you really need us to be here?" Penny asked with a sigh.

"No, you can take the ladies and leave now that we are through the initial discussion and you know you're exiled from the Convention." Sheldon stated.

"Woo hoo," Penny stated and stood, "come on girls I have a bottle of wine and the whole season of Once Upon a Time on the digital recorder, let's go oogle prince charming!"

"Bye," Bernadette and Amy stated as they followed Penny out.

Once in the hallway Penny's phone rang and flashed Commander Steve McGarrett's face.

"Steve hey!" Penny cried. "It's been so long!"

"Penny, are you with everyone?" Steve whispered.

"No, why?" she asked.

"Cause I need you're help." Steve stated, "But I don't want the guys to know."

"Ooh top secret!" Penny giggled.

"Not really, I just need you to pick us up from the Air Port if you can."

"Sure thing Commander McGarrett, when?" Penny asked.

"Tomorrow, 6am, and no one can know we're there."

"Ten four." Penny stated as the phone went dead and she turned to see Bernadette and Amy watching with millions of questions just waiting to burst forth. "Oh do I have a story for you." Penny stated and rushed into her apartment.
