A/N: In this story, Shawn has a twin sister named Lindsey. She ran away when they were fourteen and no one could find her.
Gus was sitting at his desk at the Psych office trying to figure out their finances while Shawn was getting them ice cream and "other delicious snacks." He didn`t notice the woman who had walked in until she cleared her throat. He looked up and couldn`t believe he hadn`t noticed this stunning woman. She had long blond hair, amazing curves, large breasts, and dark eyes that seemed to be out of a painting. He couldn`t help but check out her out. She was a little bit shorter than average, he noticed. He realized how long he had been staring when she spoke.
"Umm.. is Shawn Spencer here?" she asked, sounding a little amused. God, even her voice was sexy.
"Uh, he`s getting food. Can I help you with something?"
"Hmm.. I guess his appetite hasn`t changed. I just need to see him. Do you mind if I wait for him?"
"Not at all." Gus was disappointed. He figured that she must be an old girlfriend of Shawn`s, "I`m Gus, by the way."
She looked surprised, "Gus?" She jumped up and hugged him around the neck. When he looked confused she said, "I`m Lindsey... Shawn`s twin."
Gus` confused expression quickly turned into complete shock. He pulled away. Shawn`s sister had ran away during their first year of high school. Their dad had gotten the entire police department to search for her, but no one had ever found her. Shawn only talked about her once in a while if he was drunk. And then it would be a conversation filled with tears because he had never known what had happened to her. Gus was considering having her come back later so that he could prepare Shawn first, but then it was too late.
The door opened and Shawn complained that the grocery store didn`t carry peanut butter ice cream. When he saw Lindsey he froze. No one spoke for at least a full minute. Lindsey was the first to break the silence.
"Hi Shawn."
"What are you doing here?" he was angry.
"I-I wanted to see you," she was trying, and failing, to hide how upset she was by his anger.
"What, fifteen years later? Are you crazy?"
"I`m sorry," she now had tears rolling down her cheeks.
He shook his head, "Just go."
She did. And Gus wasn`t sure what to say to Shawn as he opened a bottle of rum and started to get drunk.
Late that night, when Shawn was asleep, Gus' cell phone rang.
"Hello?"
"Gus, is he still mad at me?" It was Lindsey. Gus walked outside so that he didn`t wake Shawn.
"Linds, he`s been so upset and scared for you for years. Where were you?"
"I`m so sorry for leaving him. I was afraid that if I called him then Dad would track the call or something. I feel so guilty about it. But I really have missed him."
While she was talking, Gus noticed that she was sitting in her car outside of the Psych office. He walked over and got in.
"How long have you been out here?"
"Since Shawn told me to leave. Besides a few bathroom breaks," she smiled weakly.
"He`s been wondering how you could be fine but never try to contact him." Gus was wondering the same thing himself.
"Gus, it`s really complicated. I was afraid that if I called my dad would track me down then I`d have to come back home. And when I was eighteen I should have called, but I was scared that he`d hate me by then. I guess he still does," she was trying not to cry, and Gus felt bad for her.
He waited a moment and then asked, "What happened?"
At that she did start to cry. She buried her face in her hands and Gus tried not to cry because he was a sympathetic cryer. But before he started to cry, Shawn was opening her door and hugging her.
"I`m sorry," he mumbled quietly, and Gus took the hint to give them a few minutes alone.
"Tell me why you left," Shawn asked once Gus was back in the Psych office and Lindsey had calmed down a little.
She shook her head, "I don't want to talk about it. Just please don't tell dad that I'm here."
"Did dad do something?" Shawn seemed surprised.
"No, but I don't want to see him. He'll be mad and he'll want to know why I left... I just can't tell him," she let out another little sob.
"Ok, ok, I won't tell him until you're ready, ok? But he's still really worried that something happened to you."
"I just don't want to see him yet."
"Ok, why don't you follow me back to my place? You can stay with me."
She nodded, but Shawn noticed how she was shaking.
"How about I drive?"
"Yeah, that's probably a good idea." She got out of the driver's seat and Shawn walked around the car and opened the passenger door for her.
