from the trailer this morning (which i was at first sad it spoiled post s6b zoe with 7) was so deceptive lmao. as soon as the last krillitane ep ended i knew it would be the krillitane!zoe in this one. really great story dealing with the doctor's grief and turmoil surrounding zoe/jamie's exits. i do kinda suspect that something will happen to 7 in the future maybe he finds out about s6b, it certainly teased that. really good concept with the krillitane, and a clever way to deal with them too! ray was alright, didn't think either a bad or good thing about her she was kinda just there? keen to hear more of her!
