When the Doctor was first blocked I thought it was just a social media ‘bubble’ things (pun intended) but her reaction to the Doctor and Ruby being the same room was the final ‘aha’ moment for me.

The view of social media was pretty good I thought, epseically with the advent of the Apple Vision Pro, which is basically the current version of Dot & Bubble… However, I thought the only ‘good’ person being the one that read a book once in a while was a bit heavy handed.

It would have also been interesting to find out more about the creation/rebellion of the dots and the creation of the slugs.

The episode had a bit of the feeling of Blink to me, with the Doctor & Ruby only being on a screen much of the time. Only in this one, it’s the people, in their bubbles who are the baddies…

Oh and I still want Ruby’s mum as the Doctor’s companion…
