You all ended up brining in Mark Ratner the next day down to Castle. Blindfolded of course.

You had place in a interrogation room. You and Chuck were standing off to the side as Casey did his thing.

"This is not a negotiation. Okay, Ratner, here's how this is gonna go down."

" Wait. You're our waiter. From the restaurant. Man, we really screwed you on the tip."

"You want into witness protection, you're gonna have to scratch our back, too."

"What do you mean?"

" Those two goons from last night, they don't report back to their boss, he's gonna want a follow-up meet. We're gonna cover that drop. He contact you yet?"

" I'm sorry, but I prefer to deal only with Special Agent Carmichael. The man saved my life last night."

" Is that right, Special Agent Carmichael?" Casey said, turning to Chuck, glaring at him. Chuck just stood there, not quite sure what to do.

"Y/N are you an agent too?" Mark asked looking at you now.

"Uhhh..."

"Yes! Yes this is my wife, Y/N Carmichael. And it's funny you should mention the whole special agent thing...You should really see me scale buildings with suction cups, 'cause I'm... I'm very good at that. I only dabble in the violence. So... "

"Modesty doesn't suit you, Mad Dog." Casey said.

You and Chuck looked at him weird.

"Mad Dog? Why... Why do they call him that?" Mark asked.

Casey winked at you both and you both winked back.

" Listen, I got to know where your next meet's at, okay? And I'll ask you real politely. My partner here, he's a maniac. It's... It's fine when it's to protect you, but you don't want to be on the receiving end of Mad Dog. That's how I got this." Casey showed him a scar." Huh? I parked in his spot once. This scar reminds me every day- don't mess with Mad Dog."

"It's true...my husband can be an animal." you said walking closer to Mark. "You should have seen what he did to a man who got handsy with me...It wasn't pretty."

" Now, I'm gonna ask you... Let me ask you one more time. Where's the meet?"

" Look, I-I don't know, okay? He texts me. That's it, that's all I know."

Casey looked at him then backed away slowly and looked at Chuck.

"He's all yours, Mad Dog."

All of a sudden Mark's phone went off

"No, no! I... Wait a minute. This, this is him, right now. He's-he's-he's... He's texting me right now! This is him! Okay, he wants to meet tonight. But-but that doesn't work for me. I can't meet tonight. Tonight's my reunion, and my wife has really been looking forward to this- she wants to be reunion queen. I couldn't disappoint her."

"Stop talking! You'll meet him there." Casey said.

" I... I-I don't know about this."

"No one's gonna mess with you, man. I got your back." Chuck said, acting the part.

" Okay. Okay, I'll do it."

Casey looked back at Chuck and nodded, then took Mark out. You walked over to Chuck and circled your arms around his neck.

"Not gonna lie...that was really hot." you said smiling.

Chuck smirked and winked at you before kissing you.

You and Chuck later went down to Sarah's apartment. You knocked on her door and she answered, sweating and wearing workout clothes.

"What?"

" Brought you a present." you said, holding up a box.

" Well, it's not my birthday."

" Oh, one down, 364 and a quarter possibilities to go." you said as you and Chuck walked and went to sit on her bed.

"Just open the box, hmm?" Chuck said.

Sarah opened it and pulled out a dress.

"Why do I need a new dress for?"

" I know you're gonna see this as a glass half-empty, but I think it's a real opportunity..." Chuck started.

"Spill it!" Sarah shouted.

" We have to go to your reunion." Chuck finished.

"Look, I know that you don't like talking about your past, much less revisiting it, but the reunion is where the drop's going down." you said as Sarah walked away.

"Look, I'm sorry. It's just... High school... It was a tough time for me, okay?"

" Tell me about it. We-we get that. Trying to figure out who you are and what you're gonna do with the rest of your life while constantly distracted with raging hormones." Chuck said, trying to understand her.

" I... It was more than that for me." she said looking at you both now.

You smiled softly at Sarah and walked over to her.

"Hey... it'll be okay. Trust me. Besides, everybody remembers high school way worse than it was."

You all arrived at Sarah's reunion, all dressed up. You and Sarah walked in arms linked as Chuck had his arm around you.

Your dress:

"You look beautiful." Chuck said softly to you and you looked at him and blushed. The fact that he could still manage to make you do that was amazing.

Sarah looked around nervous and you could tell.

"Sarah relax. You look great." you told her and she smiled back at you.

"Thanks Y/N."

You all then proceed to walk over to the check in table.

"Welcome Cougar, class of '98!" the woman behind the table cheered.

" Hi. Jennifer Burton?"

" Burton? Ooh, here." she handed Sarah a sticker with her name on it.

" Thanks." Sarah said, putting the sticker on her dress.

" Wait. You're Jenny Burton?"

" I am if it says I am."

You and Sarah linked arms again and you could tell it was all getting to her.

"Hey, hey. Hey, hey, hey. " you started to say softly, stopping Sarah and turning her to face you and Chuck. "No one's gonna mess with you, Sarah, okay?"

" We got your back." Chuck added. He then looked up and saw Sarah's high school photo. She definitely looked different back then.

" Wow! Oh. It's not that bad. It's not that bad." Chuck tried to reassure.

" Mm-hmm."

You just smiled awkwardly.

You all were walking around the gym, where the reunion was taking place. Chuck picked up a couple glasses of wine for you and Sarah then took one for himself.

"Remember, the only difference between high school and a high school reunion is that you don't get suspended for being drunk." Chuck said as you all walked over to an empty table. "Want to dance ladies? Fortunately for you, I was at the top of my game in '98." Chuck then started to do some silly dance moves and it made you giggle." Oh, a little bit of that. Come that, oh, and then... and then mirror that, you know, just kind of... "

Sarah saw Heather and Heather waved at Sarah then talked to a couple women and they gave Sarah weird looks and began to walk. Sarah looked down.

"What? What is it? You okay?" you asked her.

"So, my buddies and I checked out the room and picked the best-looking girl here. Decided to come introduce myself to the woman I'll be waking up with tomorrow. Or maybe two." The man who approached your table said, looking at both Sarah and you. " Dick Duffy."

" And I'm Chuck, Y/N's boyfriend, but Jenny here is off limits too... " Chuck said quickly stepping in.

"Jenny? Wait. Jenny Burton?" Dick said, shocked. "Damn! Ten years has been very sweet to you."

"Thank you."

"Ten years is a Hell of a long time, especially to someone living in an eight by ten cell. How is your dad?"

You and Chuck looked at Sarah then back at Dick and looked down at his tattoo and flashed on it.

"Nachos! I smell nachos! That's gonna hit the spot. Let's get some nachos." Chuck said putting his hands on yours and Sarah's backs, walking away. " Bye, Dick."

" I think that's him, that's the guy." Chuck told Sarah once they were far enough from him.

" What guy?"

" Duffy. We just flashed on Duffy." you told her.

"What'd you do? Attend Bad Guy High?" Chuck asked sarcastically.

"What are you talking about?"

" Well, Duffy has some kind of connection to the Russian mob. I'm pretty sure he's the guy that Ratner is supposed to connect with to hand off the super-bomber plans." Chuck said.

" Makes sense. He's always been a jerk. Okay, you go catch Ratner up, have him set up the meet. Y/N go with him actually. I'll tip off the DJ. "

"Why? Why the DJ?" you asked confused.

Sarah motioned her head and you looked over to see Casey, working as the DJ, and having quite a fun time.

You were all pretty shocked to see that.

You and Chuck were able to find Mark so you could inform him of what was going on. Chuck made sure to get into his "Mad Dog" mode.

"My bosses at Langley have informed me that that's the guy who's been texting you."

"Our target is Dick Duffy? Of course! The guy who terrorizes me in high school is now going to terrorize the entire world with my super-bomber."

" You're gonna be just fine. You have my personal guarantee. And my wife here will be watching out for you as well."

Mark discussed everything with Ratner, you and Chuck standing close by to listen in. He wanted to meet with Mark later tonight outside.

The three of you now were just waiting at a table.

"Never should have stolen the bomber plans. I should have gone right to you guys. But they threatened my wife. I wasn't thinking straight." You and Chuck nodded your heads, agreeing with him. "You see, I'm just a guy who likes math, you know, and somehow I got a beautiful girl like that to fall in love with me. I have to pinch myself sometimes. It's like I'm dreaming. Ah, forget it, Agent Carmichael. I mean, how can I expect a cool guy like you to understand?"

" You know what, Mark? Sometimes the nerd gets the girl." Chuck said looking over at you and smiling lovingly. You smiled back at him and leaned in to give him a sweet kiss.

Later, while you and Chuck were with Mark, Sarah and Casey found out quickly that Dick wasn't the guy. Little did they know, the real person behind all this... was Mark's wife Heather. And she wanted you, Chuck and Mark dead.
