Repeated Hidden Pedantic Geekdom: Colin Baker's Doctor didn't have a sonic screwdriver.
Why? Did Peter Davidson lose it? Just because he didn't use it, doesn't mean he didn't have it. Maybe anytime he went to use it he needed a posi-drive and the screwdriver was a flat-head, and so he ended up just keeping it in his pocket. Maybe the batteries ran out?
Why do I get the feeling I'm going to be sorry I even offered an opinion on this?
(I agree, Grrrrr indeed).
