Not necessarily. We all know that Shatner has a relationship with several members of the cast (you see that on Twitter all the time). So Shatner showing up at a shoot would not really raise any eyebrows. and it would cause exactly the speculation that we are having right now.

But they could film a scene with him in it without it being leaked, if they so desired.
