As you might have noticed, the last 3 chapters followed the episode quite closely. But all good things must come to an end. This is where Rodney begins to show his Dark side, and the Rodney we all know and love, goes away.

Stargate Atlantis - The Dark Side of McKay

Chapter 4 - The Beginning of the end.

Arriving at the Chair control room, McKay did a brief visual survey to see the room was clear, then sealed the door.

Without hesitation, McKay heads for the chair, sits down, and the chair reclines, after a split second, a hologram of the city appears over McKay.

Atlantis - Control Room

Sheppard arrives and proceeded up the stairs and into Weirs office, where she was researching Ancient History.

"Have you seen McKay? I can't raise him on the radio." Sheppard asked.

"He was here a few minutes ago, he asked to use the chair. When I said "No", he said he was going to his quarters." Weir replied.

"Did anyone else see him?" Sheppard asked.

"I would imagine so. Ronon was with him." Weir elaborated.

Sheppard activated the link on his headset.

"Ronon, this is Sheppard."

When there was no response he tried again.

"Ronon, this is Sheppard, come in."

When Ronon did not respond, Sheppard began looking concerned.

"I think we have a problem." Sheppard said.

Sheppard and Weir made a bee-line for McKay's quarters.

"Why am I reminded more and more of that incident at Stargate Command?" Weir asked.

Soon Sheppard and Weir arrived at McKay's quarters.

Sheppard hit the chime.

No response. Sheppard hit it again.

Again, no response.

Weir activated the link on her headset.

"Chuck, this is Weir. We need into McKay's quarters." Weir said, and after a second the door to McKay's quarters opened.

Walking in, Sheppard noticed McKay wasn't in his bed, Sheppard made his usual comment.

"He's not in his bed." Sheppard noted.

"Which begs the question: Where is he?" Weir asked.

Then a disturbing call came in.

"Dr. Weir. Someone has sealed them selves in the chair room, and they're not responding."

"We're on our way." Weir replied, while Sheppard called for a team of Marines.

"I've got a bad feeling about this." Sheppard commented, then lead the way out into the corridor.

Arriving at the Chair room Weir was briefed on the situation.

"Who ever is in there, they've managed to stay ahead of us. Blocking any way of gaining entry into the room."

"What about C-4?" Sheppard asked.

"Are you sure someone is in there?" Weir asked not wanting to resort to blowing something up..

"Positive."

Weir was handed a life-signs-detector and it showed a blip in the Chair Control room.

It was clear that McKay was in the Chair room.

Then all power was cut from the entire city.

Sheppard turned to the nearest Marine.

"We need some C-4, now!"

Sheppard stopped when he heard a voice on the intercom.

"I'm afraid I can't allow you in here."

"McKay?" Sheppard asked.

"Who else would it be?" McKay asked in a dark tone, almost sinister and mono-toned.

"Open the door, McKay!" Sheppard demanded impatiently.

"I can't do that." McKay replied.

With those words something begins spewing out of a nearby pipe.

"Fire Suppressant, get out of here." Weir shouted.

"You heard her, everyone out!" Sheppard mirrored.

Thank you, reviews are welcome, whether constructive or ego massaging. Please bear in mind I think I had to make up a few things.
