From Tardis Wiki, the free Doctor Who reference
Michael Kirkwood was a human who was captured by a Zygon named Kritakh, who took his form.
Kritakh later found Kirkwood and tried to return his body, but the unconscious Kirkwood had complications and had to be brought to St Kitts Hospital. (HOMEVID: Zygon: When Being You Just Isn't Enough) The love wraith Stacey Facade later adopted the name and appearance of Michael to try and feed on the emotions of Lor Anderson, (HOMEVID: Lauren Anderson) who had had a reomantic relationship with Kritakh while both Lor and Kritakh himself believed that Kritakh was Michael.
