He absolutely loves to troll her and she sets herself up for it, with her insults and her pomposity.
But, having just edited the chapter including the two of them and the VR set, I have to wonder if she sneakily does understand him and is only pretending not to.
And maybe he knows that, and plays along.
If that’s the case, it’s Zoe who’s actually being trolled. What would she do, if she guessed this? Roll her eyes and carry on, I imagine. Leave them to it.
