"Flynn, go!"
The words come unbidden to his mind. He shakes his head. Now is not the time for random words in his system, he has a job to do. His air craft is in a perfect position to destroy the Users and the Isos' craft… And yet something is holding him back.
"Come on, what are you waiting for? Take the shot! Finish the game!" C.L.U. says, but Rinzler doesn't compile. Then it all comes together.
His name is TRON. He was built to protect the Grid from enemies and C.L.U. is an enemy. C.L.U. tried to kill Flynn, the friend of his creator and his friend with whom he had shared many adventures.
"I fight for the Users!" he growls and returns his craft into C.L.U.'s instead of shooting down the Flynns and Kora.
"NO!" . yells as TRON rams him. The crafts both dissolve and they fall through the air. TRON rolls over into a sky-dive position and pulls out his extra air craft stick. Just as he is about to open it, though, C.L.U. shows up next to him and they have a tug fight over the stick. C.L.U. kicks TRON in the face and TRON's grip slips. C.L.U. uses the stick for a craft of his own while TRON falls into the water.
He knows he won't make it out. "Flynn, I hope I have bought you enough time." His lights flicker and go off, and then they blink back on. They are not red/orange as they were before, but blue. TRON smiles. "Goodbye, old friend."
"I fight for the Users!"
