Somewhere Different Now

Hoping to get through the last bit of S4 and the specials before Waters of Mars, I rewatched Turn Left tonight. I have a few things to say about it:

-Donna Noble is awesome!

-Rose is enigmatic, powerful, and overall doing a pretty decent job of being the Doctor, considering. However, her voice still sounds weird in this episode.

-The moment when Donna passes on Rose's message and the Doctor runs outside to see "Bad Wolf" written everywhere has to rank among the coolest moments in Doctor Who, IMHO.

-When Rose was discussing the destruction of the Sontaran ship with Donna, she says that Gwen and Ianto have given their lives and Jack has been transported to the Sontaran world. This suggests that she might already be aware of Jack's immortality. Yet in JE we see her scared and confused when Jack is shot, as if she thought him mortal. My impression of the canonical timeline was that Rose began in Pete's world, spent some time going in and out of the Turn Left world while attempting to reach the Doctor, and eventually made it back to the normal universe in brief flashes at Partners in Crime and permanently for Stolen Earth. Now I'm wondering if that's not the case. Was the Rose in Turn Left erased when Donna reset that universe? Or does Turn Left take place after JE in Rose's personal timeline? I've seen a fic or two where the latter scenario happened as Rose tried to get back to Ten either after the death of TenII or other reasons why she needed to cross dimensions. Maybe that makes sense.

-The downward spiral of the world without the Doctor is terrifically chilling. The last four episodes of S4 (Midnight, TL, TSE, JE) are all magnificently dark.

-Once more, Donna Noble is really, truly, astoundingly AWESOME!!!
