In the morning, the Doctor, Martha and Shakespeare proceed to the Globe Theatre, and the Doctor asks why the theatre has 14 sides. They decide to visit the architect of the theatre in Bethlem Hospital. They find the architect, Peter Streete, in a catatonic state. The Doctor helps him emerge from his catatonia long enough to reveal that the witches dictated the Globe's tetradecagonal design to him. The witches Lilith, Doomfinger, and Bloodtide observe this through their cauldron, and Doomfinger teleports to the cell and kills Peter with a touch. The Doctor identifies the witches as Carrionites, a species whose magic is based on the power of words which allows them to manipulate psychic energy. By uttering the name Carrionite the Doctor is able to repel her.
