"World War Two... What the hell did you do me?!" Rex exclaimed as Jack and Gwen stared in shock and bewilderment.

"I-I.." Jack stuttered, for once the confident Captain was unsure. "This wasn't supposed to happen.

"Well reverse it!" Rex demanded and pulled himself to his feet.

"Rex.. there is no way to reverse it. I'm sorry." Jack said slowly and remorsefully.

Rex's eyes widened and he shoved the Captain before storming away. Gwen went after him, knowing that she would need to be delicate. Jack stood alone in the hallway, almost frozen. He felt... strange. Almost empowered, in a way. Knowing his blood could do such things. It was daunting but amazing.

"Rex! Rex wait!" He yelled and sprinted the way Gwen and he had gone. He ran around a corner and found the agent leaning against the wall, looking out of it. Jack approached cautiously, knowing also that this would be hard.

"Rex?..." Jack says slowly as he reached his side. "Are you.. okay?"

Rex snaps his gaze up to Jack violently. "What the hell do you think?! I'm never gonna die!"

"Rex, I know this is.. daunting.. but it really isn't-" Jack said gently, only to be cut off.

"You've got no idea!" He yells angrily, turning heads. "I'm gonna have to stand by and watch as everyone and everything I know dies! I don't want this!"

"Hey, it's gonna be okay." Gwen contributes and places a comforting hand on Rex's shoulder, only for him to brush it off.

"You should have done this to Esther... not me." Rex says through gritted teeth, staring right into Jack's soul. "She should have lived. She deserved to live!"

"Rex, just come on, calm down." Gwen says and starts to lead him away. Rhys came and helped take the man to somewhere quieter. Jack was alone once more.

"Maybe I should have done it to Esther.." He muttered almost silently, barely louder than a whisper. Suddenly, he found himself remembering everyone he loved.

Owen, Tosh, Steven, Gray... He listed mentally, his heart aching with every name, until he came to the most painful and guilt-filled of all:

Ianto.

My precious Ianto Jones.

Then everything in his mind flew together like asteroids colliding. Rex's immortality, his blood, Ianto! He had an idea. A risky idea. But oh so worth it. Yes. He was sure he could do it:

I can save Ianto.
