So, Its kinda weird but, when they had this discussion about the name 'redbird' given to the drone in the last episode, I think they're trying to show us something about a 'bird'. Don't you?
Why the name REDbird?
Why the pidgeons showed at the end?
I'm pretty sure this is something relevant, and Partridge is behind all this.
How do you find this theory?
plausible
unlikely
