Let's jump right in!
Cons:
So, if we're doing this Guide/Nandor thing, fine, I guess. It feels pretty unmotivated and lazy to me but okay! But then if we're going to do this, let's do this. The two characters haven't really interacted on screen, and in this episode it's just Nandor being encouraged to be brave and tell her how he feels, and then nothing comes of it? I guess I just think... if you want to use this idea as a vector for comedy, can we at least see some jokes being told about it?
With the knowledge that this show's ending is creeping up on us, I do wish I felt like this episode furthered Guillermo's plot a little more. It seems like it's just another episode reinforcing him as a loyal sycophant. The stuff with Colin was funny, but the episode ends with Guillermo happy and excited to be serving these new masters. I want him to like... foment a revolution, or quit, or something dramatic. Hopefully we'll get to see that soon.
