On TV's The Flash, when a villain is too powerful to be held in a conventional prison, they're brought to The Pipeline -- a power-dampening series of cells deep within S.T.A.R. Labs.

And while we occasionally see members of the main cast bring the bad guys Big Belly Burger -- mostly when they need to interrogate them -- some fans have asked how exactly the prisoners are usually fed, how they use the bathroom when there doesn't appear to be anything like that in their cells, etc.

According to series regular Carlos Valdes, this is something that they've actually talked about, even though the explanations haven't really made it onscreen yet. Well, the bathroom part hasn't, anyway.

Recounting a deleted scene from "Grodd Lives," in which Caitlin brings a cart full of custom-ordered fast food to the prisoners, Valdes said, "I think there was also a scene where there was a toilet in the Pipeline..."

...he then trailed off, not wanting to get too intimate with the specifics of the prisoners' bathroom habits.

Of course, how that toilet would work with somebody like The Mist, who could use external pipes to escape, is anybody's guess. We certainly imagine they've got it all worked out considering that we recently learned that S.T.A.R. Labs even has its own morgue onsite.

But if you're really stressing out about this, we have another video to suggest for you...

The Flash will go into production on its third season in July with an eye toward an October premiere date. Expect more news, casting and the like between now and then, particularly around the time of Comic Con International: San Diego.
