That was an amazing tour! I do know that Little Shop Props used to be on etsy, but seeing them on display here is pretty cool. That Davros looks lovely too!
Rtd simply just doesn’t want to use a disabled character as a villain as the trope can be seen as having some moral problems. So if he were to make a story with the character, he simply would use the character before he gets disabled from the bombings the Thals did on his base.
