I don't blame Ianto for being annoyed. I would be too. He seems to be the one that does all of the cleaning. They should install some kind of shower or something when they come in so they clean off before they enter the rest of the Hub. Great story.
Author's Response: As long as they shed their clothes in the garage it doesn't leave a mess elsewhere, and there's a quick route down to the locker room showers as well as the decontamination ones. Most of the team seem incapable of cleaning up after themselves. Thank you!
