Steven Page

From Tardis Wiki, the free Doctor Who reference

Steven Page worked with the Perseus Corporeal Stephen Le Page, though he thought Le Page was human.

Page and Le Page imprisoned the Third Doctor and Jo Grant when they were apprehended for not having PANs. They placed implants in the Doctor and Jo, designed to keep track of them. Page entertained Jo while Le Page had a private conversation with the Doctor. (PROSE: /Carpenter/Butterfly/Baronet)
