Chapter One: Betrayal

"God I'm so nervous. Wait! what if he doesn't like the gift." Rigby said, a slight panic raising in his voice as he walked out of mall with a gift bag.

"It's your anniversary I think he'll like whatever you bought him and if he doesn't like it then keep the receipt and get your money back." Ilene said walking next to the boy patting his back.

"Okay. Thanks for the reassurance Ilene." He said, looking more relaxed and looked down at the gift he got Mordecai.

A wireless headset to play online games with he had it personalized with a detectable blue heron wing on the side that had the microphone.

Annie are you okay, are you okay Annie? You've been hit by… You've been struck by… A smooth criminal –

Rigby's cellphone rang with 'Smooth Criminal' by Michael Jackson- the ringtone that Margaret insisted that be her personal ringtone for his phone-

"Why is Margaret calling you? Isn't she supposed to be at work." Ilene said starting up her car, her voice full of curiosity.

"Don't know, I'll put it on speaker phone." He said activating the speaker phone.

"Hey Margs!" Ilene shouted as she pulled out of the parking space

"Hey what's up." Rigby said into the phone and heard nothing for a moment…

…Until they heard the owner of the phone moan something inaudible

"Hey turn down the radio, I heard something." Rigby asked while listening closer to the phone.

When the radio was turned off they heard moaning from the other end then a familiar voice, as clear as day, say "We'll never make to the bed if we keep on like this."

"Is that-" Ilene started

But Rigby cut her off with "It can't be! Take me to the house quickly."

He said, taking hold of the 'holy crap' safety handle as Ilene floored it down the interstate and to the off-ramp to the park's boarding house.

By the time they made to the house the sun had already set, they barely had the car parked before they ran up to the front door and proceeded to bang on said door only to be opened by Mitch otherwise known as 'Muscle Man', who looked quite taken aback by seeing the two young adults catching their breath at the door.

"Rigby what are you doing out here I thought that was you with your boyfriend upstairs." He said, surprise ringing clear in his voice.

"But that could only mean that…" he continued but was stopped as the two people bolted past him and to the stairs, in which he followed close behind.

When they made it to the door they stopped to listen to whom was inside and it was quiet.

"Maybe no one's inside." Mitch whispered then they heard footsteps moving closer to the door, in response they moved to the end of the hallway, hiding around the corner, turning around just in time to see Margaret walk out of the room with Mordecai coming out behind her, both readjusting their clothing as they exit and not noticing the three people peeping around the corner.

"Babe next time not so rough, I'm probably not going to walk right tomorrow." She said.

"Sorry about that it's hard to hold back with you." He said holding her arms, kissing her on the forehead, and she on impulse wrapped her arms around his waist pulling him into a hug.

"It's looks so natural…More natural than when we do that" Rigby thought sadly while looking at the display

"Walk me to my car please?" she said.

"Sure" was the reply as they walked away the trio just stood there watching:

Ilene= appalled

Mitch= shocked

Rigby=?

"Where did he go?" Mitch asked because Rigby was no longer by their side and was in his room pulling some clothes out of the closet and into an overnight bag

"Where are you going?" Mitch asked when they reached his door

"Out of this house, I'm taking the back door so he can't see me." He said zipping up the overnight bag and grabbing the gift bag

'Ilene I guess you were right about the receipt thing huh?' He thought while walking out the room, down the stairs, and to the kitchen where the back door was located when he was stopped by Benson.

"What are you doing here, I thought that -" He started

"Well you thought wrong! Like I did." The brunet snapped feeling tears stinging the corners of his eyes. Upon seeing this –because it's rare to see him cry in public- Benson knew something wasn't right

"Go know and tell me later." He said touching Rigby's arm

"Thank you."

"Let's go I hear the front door." Ilene said, quickly opening the back door and running out of it with Rigby following close behind and quietly closing the door and running to the passenger side of car, when he was buckled in Ilene smoothly pulled out of the parking spot and hit the road

"Where should I take you." Ilene asked.

'To be honest I didn't give that any thought…' His thoughts trailed off

-There is one person and you know it.- His mind countered and as much as he didn't want to admit it but this is his only option.

"2735 West Point Drive." He answered

{20 minutes later}

"Will you be alright?" Ilene asked while Rigby was getting out of the car

"Yeah hopefully. Don't tell anyone where I am okay." He said and hugged her thanks and closed the car door and walked up to the front door of the huge two story house while Ilene pulled off.

Taking a deep breath he pressed the doorbell and waited for someone to answer the door.

When the door opened his mocha brown eyes looked up to a pair of warm chocolate brown eyes {and by 'looked up' it meant a 5'9 person looking up to a 6'1 person}

"Rigby." The young man said.

"Um… Hi Don." Rigby stammered while looking at his brother.
