I could sort of understand the Rogue cameo, because the actor had other commitments. Yet why even bother at that point? Did they feel like there needed to be some sort of "farewell" to Gatwa's Doctor? Will we ever hear about him again or is he just lost to Super Hell?
I know! I'd rather not have seen him!

I had forgotten The Library! And River Song ended her life there, with two children she knew weren't real! That never made sense to me and was an awful way of getting rid of the character.

I had really hoped to see Susan again while the actress is still with us, but you're right—we have no idea how long it might be.

There are so many good actors, and they don't even have to limit themselves to the UK, really! Like the US, the UK attracts actors from elsewhere who want to make a career onscreen or on stage, so they shouldn't be hurting for choice!

Just so disappointed in the episode!
