Not a bad episode but not one of my favorites for sure

We get the return of Cassandra, this time with a body swapping ability that creates some funny moments. The Doctor destroys the cat nun's laboratory and frees all the diseased slaves. I think this could have been a more interesting situation if he got to see the effects of that on the medicine of New Earth. The way he cures them is kinda nonsensical but it's handwaved, I don't really hate it that much

Maybe this episode would have been better with a little shop
