Why is RTD suddenly thinking the Sonic Screwdriver looks like a gun ???

It's such a dumb thing to say, if he even really said it. The whole point of the screwdriver is that it never looked or behaved anything like a gun. I'd never have made the association in a million years. If anything it was a magic wand pretending to be a piece of technology.

But also isn't there a clip in the trailer with Ruby holding a massive gun too??
