Chapter 3

Shawn was pissed. He had ran after the bike yelling at Gus, then trying to find him had to walk for miles in the dark, all for nothing. Shawn decided to go back to the Psych office, and when he got there, his bike was parked outside. Shawn stormed through the door, ready to give Gus a piece of his mind, only to find him asleep on the big chair behind the desk.

Shawn walked in slowly, and stood looking at his lifelong best friend. Gus was sleeping with his mouth slightly open; his dark eyelashes fluttering sometimes against his cheek. This face was more familiar to Shawn than his own, but the man who had been masquerading as his Gus lately was a completely unknown person.

Shawn picked up the ceramic pineapple paperweight from his desk and put it down again, loudly. Gus jerked awake with a start.

"Huh…"

"Gus? Are you ok?" Shawn asked.

"Shawn..?" Gus looked around himself. "Did I fall asleep in the office? Do we have a case?"

"There is no case, dude." Shawn said, growing increasingly more worried, "Gus, do you know how you got here?"

Gus looked puzzled; 'No…" he said after a while.

Shawn sighed deeply and walked around the desk to stand beside Gus. He put his hand on the other man's shoulder, the solid warm feeling reassuring him a little.

"Gus, you kind of hijacked my bike, pushed me aside and rode away into the night." Shawn announced; Gus stared at him. "After a couple of hours of running around looking for you, I came to the office and found you, passed out."

"It's… just the stress; I haven't been sleeping that well… It's not extraordinary to have a blackout!" Gus reasoned.

"It's not just the blackouts!" Shawn cried earnestly, "What about the way you behave right before that? You become like this whole different guy! And later you can't even remember it!"

"You are exaggerating, Shawn, just because I took your bike for a spin doesn't mean that I went bananas. I guess I just wanted to blow off some steam!"

"You didn't seem to know me! ME! That's not normal, Gus! It was like aliens invaded your body or something."

"Okay… there's no need to get all freaked out, Shawn; I'll just go home and get some sleep. It's this sleep deprivation because of overwork that's been throwing me a little off my game." Gus got up and stretched. " I'll become alright in the morning." He smiled at Shawn.

"Gus…" Shawn said slowly, "This has happened twice already. You need to see a psychologist."

"I am not mad!" snapped Gus. "I don't need some stupid psycho doctor probing into my mind."

"Of course you are not mad," Shawn soothed, "But maybe this…err, stress problem you have could be worked out with some professional help…"

"Problem? I don't have any problem, Shawn! So I took your bike out for a ride or behaved a little differently one evening; big deal!"

"Gus…"

"I have put up with every crazy episode you have had over the years!" Gus exploded. "Did I once tell you that you were insane? Didn't I take everything in my stride? I just act a little unsteady one night and you freak out and try to send me to a loony doctor! Some pal you are!"

Shawn winced at the yelling. He could see Gus was not happy with the idea of going to see a psychologist. But he really thought the problem Gus had needed some looking into.

"I am not freaking out, Gus, I just think that a doctor would do you good; I am just trying to help. Please understand that."

Gus took a deep breath and shook his head. "I am going home, Shawn. Good night." He started walking towards the door.

Shawn grabbed his wrist. "Gus, really…" His words were cut off by Gus whirling around and pushing Shawn against the wall.. Shawn stood transfixed as Gus advanced on him. There was a strange fire in those familiar brown eyes.

"Gus, what are…"

Gus' hands grabbed his collar.

"Don't call me that…" he hissed, " I am Burt; Burton Guster."

Shawn gasped. What had happened to his Gus? Had some evil doppelganger taken his place?

"I know you are Burton Guster," he squeaked, "But I have always called you Gus, remember? It's your nickname. In fact everybody…"

"Shut up! I have no such nickname." Gus shook him by the collar, "I. Am. Burt."

Shawn raised a hand to touch Gus' hand on his collar. "Gus, don't you remem…"

Suddenly Gus leaned in to press his mouth forcefully against Shawn's. Shawn did not get to finish the sentence. He forgot what he was going to say anyway.

A/N: Cliffhanger! Even I don't know what's going to happen in the next chappie.
