"LET ME SEE HER!"
You got back to the hub alright, Ianto somehow swept out of the way by Tosh, and had to have a talk with your dad.
Because there was only one way to get your body back.
And it might not work.
"Are you sure you want to go through with this?" Owen says, even he's unable to hide his pain at what you've been through - and what you'll have to go through.
"There has to be another way," your dad says, pacing. He's not ready to let you go. What parent ever is?
"Dad," you say simply, still not used to your voice, "I have to die. How many times have you regenerated from nothing?"
He just glares at you, saying, "This is different. We don't know how many lives you have, if you'll live through this!"
"It's only different," you reply, "Because it's not you. I've got your genes. I've already died and come back once-"
"And once should be enough," Jack cuts you off, "You're my kid! I'm not supposed to outlive you!"
You just hang your head. He is right, there is an element of risk and you know it. But you can't stay like this and you both know it, which you tell him.
He just sighs and nods. You already opted out of going with the others - having a robotic body wouldn't be the same and you wouldn't be safe on earth if you had one - and now this is really all you can do. You seem to be dying a lot, lately.
"Alright," he finally concedes, his voice showing his age for the first time, so very weary, "Let's do this."
Ianto, meanwhile, was still in the base. Oops.
Tosh brought him down to the library, at first, but that just broke him into tears so they moved to a greenhouse they'd built.
By the time he pulled himself together, Tosh figured you were gone. So she let him use a computer.
The two heard the entire conversation.
And that's why, at the very end, when you were laying on the table and they had the headpiece mostly dismantled, Ianto came in with a shout of, "LET ME SEE HER!"
"I'm sorry!" you hear Tosh say, "I couldn't stop him!"
The cameras that serve as eyes, while no longer bolted on, are still connected. So you can see the pain on his face as your dad holds him back.
"Fuck, Ianto," you hear your new voice say, "I didn't mean for this to happen. I'm sorry."
"I'm almost done and I can't stop now," you hear Owen whisper from behind you, "Say your goodbyes."
"Ianto, listen to me, before I go-" your world starts to fade, ice and pain starting to cloud the edges of your mind. You just barely manage to say before the vocal drive shuts down, "I love you."
And then you meet the dark again.
This is the first time dying hurts.
