The effects that a hypothetical trans-Plutonian planet would produce on the orbital distribution of the Classical Edgeworth-Kuiper-Belt, has been surveyed for different physical and orbital parameters of the hypothetical body in Melita et al. (2003a). The best fits were obtained by a moderately eccentric and inclined Earth-sized object with a semimajor axis of ~ 70 AU. However the history of some objects in the `Extended Scattered disk´ still represent a puzzle. One possibility is that they can be `extracted´ from the Scattered disk by the planetoid. In this work we confirm that such an hypothesis would not explain the present orbit of 2000 CR105, given the conditions for a gap as observed to be formed in the Classical EKB.
