:-D I have a love hate relationship with that episode... much how I feel about Sherlock's Belgravia...
*glomp clings Amy and Rory* (Which reminds me I do want to write my Post Angels Take Manhattan piece...
I'm hoping that Oswin isn't the same Oswin that we met... just because if so it's another River Song (Loved River in Seasons 5-7) where the Doctor knows she dies and how but still interacts with them/loves them (although I don't and can't see River in a shippy way since the season 6 reveal it hits two many squicks) and watching a companion knowing in the end she'll be awesome and have the most profound and sad conclusions to an episode I'll ever see... might break me. We need another companion that goes back to their old life only better for knowing the Doctor and less doomed/sad endings. Amy's ending was horrid (did she end up with Rory, her conclusion doesn't say and Amy would lie to the Doctor without problems, also her and Rory were happy in their lives and were sent back to a time where they had no existence/ certain rights didn't exist/ male nurses weren't common... and all Rory's training would rely on techniques that didn't exist).
I'm sort of dreading that Oswin's story might be so just because backwards time, where only the Doctor and viewer know that the person will die (in most cases a horrible death): Madame Pompadour and River Song for example...
