[doctor who] so been catching up with the current season and I've got [spoiler] questions

mostly in the case of sometimes when these characters talk I genuinely can't understand what they're saying which is. a weird problem for me to have given I went through a hella anglophile phase myself

but like okay, the nightmare episode with the gods and syria. so doc's got herself a dream about the Timeless Child (and then gets out of it because she's the doctor and she's got plot armor I guess), graham dreams about grace and his cancer returning, ryan dreams about leaving his best mate while the earth burns itself to a crisp

yaz dreams about...that...time she was going to run away from home but a nice officer talked her out of it, kind of, sort of, only it had her sister there instead, and also, nothing nightmarish at all was happening, and also everything was fine?

also she and her sister were sad about......ssssomething. I wasn't sure if we were supposed to know what. something they have dreams about--was it. was it this? are they just sad about that time yaz ran away from home?

there was something about an anniversary. I thought the parents were out bc they were celebrating their anniversary but mom said she thought they were celebrating some kind of sad anniversary and the parents being gone was just uhhh coincidence I guess

yaz's whole story in that episode, I didn't follow it and I don't know if it's bc I missed something or if it's something that we the audience don't actually know yet

also: with the shelley episode. I guess the cyberium is kind of like the cyberiad only it knows the entire temporal history of the cybermen and also doesn't have a personality? do the cybermen need Yet Another MacGuffin?

I genuinely thought we were talking about the cyberiad for a while and was confused why the doc didn't remember being half taken over by it and being Mr Clever

I guess that's not really a question just sort of a me huffing a little

but please if anyone has any insight about yaz, gimmie
