Jack/Ianto Tardis under Torchwood
I haven't read Torchwood fic in a while but this popped in my head today and I'm desperate for a reread. Ianto goes a little crazy and his brain is taken over by a Tardis under Torchwood. No one knows what's going on they just kind of let him do what he wants. Jack might have been gone and is very upset when he comes back and sees crazy Ianto? Details are very vague I know. Ianto raises the Tardis, the master and doctor are involved somehow.
Help?
