Have just watched episodes 12/13 and wow.
Don't click link if you don't want to read spoilers
Jack kisses Ianto in front of everybody :)
Everybody survives, including Rhys.
The fact that Rhys appeared to dead in the trailers meant that I was fairly sure that he wouldn't actually die because they would never give that much away in a trailer - ok I could have been wrong but i'm glad that I wasn't.
So all the spoilers floating around that say a character dies and the spoilers that say all them will be back next season are both true.
Still don't get the Belis guy at all, who or what was he and did he die or didn't he?
Did all the people killed by the shadow of the Abadon thing stay dead? If so lots of explaining to do. Same for all the plague people.
Also they should all listen to Ianto a bit more when he is reading out information, because he was about to start reading something out about Abadon when Jack interupts him at the start of episode 13.
So who will be left in charge while Jack's off with 10 - It was the TARDIS noise wasn't it?. I think it should be Ianto.
My brain is mainly melted now so i'm going to stop writing.
