The fourth episode in the sixth series of Doctor Who 'The Doctor's Wife' was alive with references to the series' themes and mysteries, so it probably would have been really difficult to not pay attention.
I'm almost certain there were many red herrings amongst the "clues" we were given, but I'm completely uncertain which of the "clues" could have been aimed at throwing the viewer off course. As I've mentioned before, I love mystery, and good writing would have all questions answered in the end - which I'm more than confident will happen in the case of this series of Doctor Who (albeit probably a few loose ends to tie-over until next series).
The transportation of the Doctor's TARDIS matrix into a human body brought us wonderful interactions (and flirtations) between the Doctor and his TARDIS in human form, played by Suranne Jones, as Idris, or 'Sexy' (his name for the TARDIS when they're alone). The inevitable parting of the Doctor and Idris made the exploration of their relationship rather poignant.
There were many moments to love within the episode; for example, Idris telling the Doctor 'I always took you where you needed to go' and her referral to him as her 'thief'.
Amy's pregnancy is a complete mystery; with the "negative/positive" scan, Amy being kidnapped by the Silence, and, now, possibly, the Doctor and his TARDIS planning to make it possible for them to interact again..?
Idris's expression becomes thoughtful when the Doctor tells her 'We are going to build a TARDIS.'
The Doctor also mentions to her, 'Wouldn't it be amazing if we could always talk, even when you're stuck inside the box?!'Was this a clue or possibly a "red herring"?
House messing with Amy's head, and making her believe Rory was dead (again) was fun. I also thought both Amy and Rory running from House was fun. These two are easily my favourite companions since the 2005 reboot.
Overall, the episode was highly enjoyable, and fun. I thought the Doctor's TARDIS in human form was brilliant. And; as Idris's body burnt-out, I felt genuinely sad the Doctor would never be able to interact with her again...
