In Series 11, Episode 1 of Doctor Who, entitled "The Woman Who Fell To Earth", there's a scene near the start with Ryan holding an object. Here's a screen clip taken a little over 3 minutes from the start.
In the scene, a series of geometric shapes appears in the air, and later a solid object appears. Ryan holds a reddish, flashing object in his hand after 'touching' the shapes and before the solid object appears. He doesn't seem to be holding the object before approaching the shapes, nor does he have it in his hand after the solid object appears.
The object resembles a 'circuit' appearing later in the episode.(Spoiler alert)
The object resembles a 'return circuit' appearing later in the episode, but it hasn't been introduced or found yet at this point in the story and there's no explanation for how Ryan got hold of it. Maybe it materialised when he pushed the 'button', or it might have just been the actor grabbing a prop at the wrong time. With Doctor Who, seemingly unintentional stuff sometimes turns out to be intentional.
What is Ryan holding? How did he get it, where did it go, and does it have anything to do with the circuit from later in the show?
