A/N set after CoE day 4, because i hated the way that ended and was crying for a while. Just a small change to make me happy, and because I hate that he died.
Spoilers for CoE day 4 and onwards.
Jack just sat there, unable to move, just staring at Ianto's body in the sports hall.Gwen had left hours ago and all the lights had been switched off. Jack was trying continuously to bring him back. The one man who brought meaning to his life... The one man he truly loved... Would never forget. Jack kept thinking back to when he revived Ianto back when Lisa had almost killed all of Torchwood 3. Back when Tosh and Owen... Back when they were a full family, not just half of one. jack kept thinking that maybe he could do it again. Bring him back with a kiss, just like last time.
If the lights had been on, Jack might have noticed Ianto's eyelids flutter, as if he was just dreaming. Jack had ignored Gwen when she mentioned seeing it, because when Jack looked himself, Ianto was as motionless as he had been. Jack then sent Gwen home with Rhys, thinking that she was hallucinating because of lack of sleep, mixed with her condition.
Jack had thought about it, so much so that he was crying when he sent Rhys home with Gwen... Those bloody beans. He knew that he shouldn't blame Rhys for that, but he knew that Ianto would not have been impressed, had he been blaming himself. He couldn't help it though. He missed those beautiful welsh vowels and knew that it was his own fault that he would never hear them again. If he hadn't hired Ianto after the Pterodactyl capturing. If he hadn't then Ianto wouldn't have had to lose Lisa and Jack wouldn't have had to be a monster and order Ianto to execute his own girlfriend.
Jack got up to leave and saw that Ianto still had his gun stuffed down the back of his trowsers. Jack bent down to get it, and had a thought. He began formulating a plan out loud, since no-one would hear him anyway and think him a madman.
"Oh Ianto, why did you have to leave me? It's ok though. I'll find a way to be with you forever, even if it means shooting myself for the rest of my life, just a few moments with you at a time is all i ask... I'll start as soon as possible." Jack looks down at the gun in his hand and sighs. "Well, no time like the present." Jack pulls the trigger to the sound of silence.
During Jack's monologue, he manages to completely miss Ianto's revival. It's more subtle than Jack's usual theatrics and so he doesn't blame the man for not noticing. But when he hears the gun and properly comes to his senses, he realises what Jack has done...
"I'm alive. How in the whole bloody universe am I still alive? Jack, where's Jack? I heard him speaking earlier, so where is he no-" Ianto looks to his left and sees Jack lying there, on the floor, motionless. "Damn it Jack! Why? Why did you have to do that? You know i hate it when you die." Ianto was now on the verge of tears, when he hears that tell tale gasp of breath, like someone coming around after almost drowning.
"DAMN IT!"
Ianto flinched, he always hated it when Jack got angry. "Jack?" He asked cautiously, almost as if he was scared of him.
"Great, and now I'm hearing things. Today couldn't get much worse, could it Ianto?" Jack looks at him casually before looking away again. Ianto waits for it to sink in and you could hear a pin drop. Ianto could see when it struck him. That Ianto was actually sat next to him in all his living glory. He just wasn't prepared for what happened next.
