This is only the prologue to the actual story. Bear with me, it should only be two parts, and gives some of my personal insights into the final fight and scenes before and after.
-------------------------------------------------------------------------------------------------------------------------------------
Saren looked down at Commander Rick Shepard – Spectre with an attitude, unbelievable accuracy, and a hell-bent determination. That determination was the thought of killing Saren, stopping the Reapers from using the Citadel to destroy all space.
The turian had been under the control of Sovereign, a Reaper that was a manipulative ship. Now, talking to the commander had let him break the spell for a short while. With his freedom temporarily restored, he told Shepard there was nothing that could be done.
"The implants…Sovereign's using them to make me do his bidding…" Sweat rolled down Saren's forehead, showing that going against his 'master' took an enormous amount of effort. His icy-blue chest heaved up and down, each breath a struggle to take a free being.
Slowly, he grasped his pistol harder, bringing it up to eye-level. The barrel pointed straight at Shepard but quavered; the turian didn't want to shoot the human standing before him.
"Don't do it, Saren," Garrus said in a blunt, commanding voice. His eye, black as night, fixated on the Spectre aiming a loaded gun at Shepard's head: Shepard, the human whom Garrus had idolized for his bravery, cunning, and prowess. Quickly, he reached behind his back and pulled out a black assault rifle. Cocking the gun, he aimed at Saren.
"You pull your trigger, I'll pull mine. Don't. Do. It."
Closing his eyes, Saren replied, "I can't stop myself. Sovereign's control is returning; it's too late."
Shepard cocked his head to the side, and looked at Saren. His voice wasn't deep, but it a certain grit in it that struck fear into every sentient being in Citadel space. The red light coming from the fires and destruction around the tower lit up his brown skin and eyes as he said, "It's never too late."
These words found their way to Saren's nearly dead heart. Slowly, it revitalized his will; once again, he had the power to move himself. "That's right…" He opened his eyes. His arm was shaking, but he was able to lift it and stick the pistol's barrel to the side of his head.
Feros colony
The council looked head-on at Saren and Nihlus, who stood perfectly in military fashion.
"Welcome to the Spectres," the Asari councilor said.
"It's an honor," Saren replied.
"For me, as well," Nihlus replied.
Saren turned to the fellow turian beside him. "Protect Citadel space until the end?" he asked.
Nihlus nodded.
"Until the end."
Citadel Tower
The memory flashed by Saren in an instant as he bid them farewell. "Thank you, Shepard…" He pulled the trigger.
The blast of gunfire echoed throughout the otherwise empty tower summit. Saren's eyes rolled into the back of his head as he fell over the platform and plummeted down to the small atrium below them. As he reached the halfway point, his body shattered the glass ceiling. Shards fell with him as he hit the bottom. There Saren lay, lifeless.
Shepard sighed. "It's over…"
Wrex nodded. "Finally. It's about time we ended that damn turian's killing spree."
As he looked down to the corpse, Shepard muttered, "This is what you died to help accomplish, Kaidan…thank you…" He turned to Wrex and Garrus. "Let's go down and make sure he's really dead."
Citadel: Space
"We need all our ships firing at Sovereign!" Joker screamed into the communications device. "I don't give a damn if the Council's on your ship! We need all the firepower we can get to take that thing down!"
He turned back to the full controls. "Alright, Joke. Aim for the head, then squeeze the trigger and never let go." He slowly closed his eyes. "Not even death could pull my hand away from the trigger."
Citadel Tower
"He's dead, all right," Wrex said as he shot. He put his pistol away, and turned to the huge glass window behind the Council area.
"Now we just have to defeat Sovereign," Garrus said.
Unbeknownst to them, however, something stirred behind them. Shepard was the first to sense it.
Quickly, he spun around. There floating in the air above them, was Saren.
