It was late but after the week Addison had all she wanted was to curl up with her boyfriend and have the memory of her mother's death disappear for a while. She walks into the door of Sam's house and right away she knows something is off. There was something eerie in the air and that's when she saw it. Naomi's prada shirt was laying on the stairs. No. This couldn't happen. They wouldn't. Addison would later wonder why she didn't turn and walk out the door. She'll look back and think that if she hadn't gone up the stairs and into Sam's room the image of them in bed together would never have been imbedded in her memory. But she does go up the stairs and she does enter Sam's room. And she did find them in bed together.

"Oh my God." Addison gasps. Sam and Naomi break apart and immediately start to try and explain themselves. But Addison had zoned them out. As they talk she cries and when their finished she tells Sam the one thing that came to mind.

"I'm pregnant."

…...

Amelia had begged Addison not to go. Addison insisted she needed a little time away. She told Amelia she just needed to clear her head. But if Amelia really thought Addison wouldn't come back she'd have gone to Seattle with Addie.

"Amelia where is she?" Sam asks Amelia three days after Addison had caught them. "At first I thought she just wasn't coming to work but now….."

"You have no business asking me Sam." Amelia hisses standing from her desk.

"I love her Amelia! I shouldn't have done what I did with Naomi but I LOVE Addison. She's having my baby." Sam tells her as he blocks the door.

"Well I guess you should have thought about that before you screwed her best friend. Now get the Hell out of my way."

Addison had expected Callie or Miranda to pick her up from the airport but to her surprise it's Mark and Derek. They didn't have to say anything. In a way she was really glad to see them. They hugged her and offered to kick Sam's ass.

"How could he?" Addison whimpers once they get back to Mark's apartment. They'd refused to let her stay in a hotel.

"Oh Addie, he's so stupid." Mark says as he holds his friend close.

"I can't believe Naomi would do that." Derek adds shaking his head. "She's your best friend."

"EX best friend." Addison corrects with a small sob. "I don't know how you forgave Mark and I Der."

"Addie you know that was different." Derek says softly rubbing her back. "I wasn't there like I should have been, I know that wasn't the case for you and Sam. He said you guys were doing really well the last time I talked to him."

"My mother died. She died after her WIFE died." Addison whispers. "I was a little distant at the funeral and I pushed him away. So I guess it wasn't that different."

"No Addie." Derek tells his ex wife warmly but firmly. "He shouldn't have cheated. He knew how hard things were for you Addie. He had NO excuse. Do not blame yourself."

"What am I going to do?" Addison asks tearfully laying her head on Derek's shoulder. "With the baby I mean."

"You should stay." Mark suggests. "We'll help you."

"I can't. Not yet anyway but maybe after I go home for a little while…."

"Addison whatever you do promise me you won't let him off the hook.," Derek says. "After the prom sex you should have hated me,"

"We've all made mistakes but this...this is unforgivable." Addison assures.

…..

Being back in LA proved to be much harder than Addison had expected. She wanted to go back to Seattle the moment she left the airport but she didn't. She went home locked the door and curled up in bed for the remainder of the day. When Amelia got home she told Addison that Sam and Naomi had asked about her repeatedly but Addison didn't care. She had decided that the baby was the only thing she was going to worry about.

Addison enter Oceanside wellness the following morning and forces herself not to cry. If she hadn't put so much money into the damn practice she'd quit.

"Addison." Charlotte says when Addison exits the elevator. Sam and Naomi look up. "I need to see you in my office." Without a word more Charlotte pulls the redhead along with her.

"What's up?" Addison asks sitting on Charlotte's couch.

"Nothing I just thought I'd get ya outta there. Amelia's at the hospital with Pete and Violet so I wanted to...ya know keep ya away from them." Charlotte explains with a small smile. Addison returns it gratefully.

"Thanks Charlotte."

Addison had successfully managed to avoid both Bennetts until lunch. Sam had been paged to the hospital and Amelia and Violet had kept Naomi away from her. She knew it was only a matter of time until she'd be forced to speak to them but for now she thought she was doing a very good job of hiding, That is until Naomi managed to sneak into her office unnoticed.

"Addie…" She says when she walks in to see Addison crying. "Oh God I don't know what to say I-"

"Get out." Addison demands as she stands up. "Don't say anything just get the Hell out of my office."

"Addison c'mon I'm your best friend."

"No you're not!" Addison yells causing Charlotte, Amelia and Violet to enter. "You stopped being my best friend when you fucked my boyfriend. I know you never approved of me and Sam but I didn't know you hated me that much. Well congratulations Naomi you got what you wanted!" Amelia hurries to Addison's side.

"Addie, Addie calm down think about Boo." Amelia reminds her. With mention of her baby Addison slowly sits back down.

"Addie I am so sorry." Naomi sobs. "But Derek forgave Mark."

"That was different. Mark is Derek's brother but you….you're nothing to me."
