Detention
From Tardis Wiki, the free Doctor Who reference
Detention was a form of punishment in school.
In November 2016, Miss Quill placed Charlie, Ram, April, Tanya and Matteusz into detention to keep them out of the way as she tried to get her arn removed. During the detention, the group were transported into no time and no space. (TV: Detained, The Metaphysical Engine, or What Quill Did)
