Hey. Something I noticed on a second watch of today's episode is when Idris/Sexy died/dissolved/went back into the machine, just after the Doctor says "I don't want you to", if you listen very very carefully, I'm faaaaaaairly sure that you can hear her whisper "I love you". Have a watch on I player - 41:40.

Unless my ears are playing tricks on me I thought it was an excellent touch to a brilliant episode! Just thought I'd bring it to everyones attention since it was super subtle!

I didn't hear it during the episode (mainly because my TV signal took that moment to break up. Grr) but I did hear it when they showed that clip on Confidential.

i didn't pick up on it first time around, but noticed it when i watched it back on iplayer. Lovely touch.

Yes she did.

I think we also hear her laugh - mixed in with the usual Tardis noise - right at the end, just after the lever moves by itself. It's kind of buried amongst the other sounds - just "ha ha ha" as he runs around the console. If that's true, it doesn't quite fit with the notion that the Tardis can't talk but as a bit of poetic licence, it's sweet - the Tardis showing that she's enjoying going off on another adventure with her man.

Same here, but nothing to do with signal loss, just didn't hear it in the ep.

Yeah, there's a laugh.
