Doctor Who Thread III: Reverse the Polarity of the Neutron Flow

[Calemyr]

However, i am upset by the doctor forgetting that ood are not servile innately.

Is that in episode 4 or 5? Because in 4 he just says "conditioned to serve", as in the Ood was already converted and the Doctor can't really do anything about it, so there's no reason to get between him and what he wants to do. Can't see 5 at the moment, though.
