With all Torchwood gets into situations they’d be needed and with all the things Torchwood stamps their logo on… would there be Torchwood logo condoms?
I would guarantee that at some point someone got Torchwood condoms made as a practical joke.
Jack swiped the box. Or maybe Owen.
Owen and Gwen conspired and left them on Jack’s desk. Jack thought that it was the funniest thing in the world and asked Ianto if they could use them, which was where Ianto drew the line.
Yes.
I also like to imagine Jack wearing boxers with the logo on it. And Ianto either laughing until it hurt or rolling his eyes.
