I’m wondering what side effects Clara might experience after becoming the Impossible Girls in Name of the Doctor. Here is what we have seen so far:
(1) Clara was able to open the TARDIS door with a voice command and close the door with a snap of her fingers.
(2) Clara was teaching a history class of some sort at the beginning of Day of the Doctor. Did she get her knowledge of history from living all the Impossible Girl lives? I suspect this is not a coincidence!
(3) Clara was in the Dark Archive before but didn’t initially remember it. It’s possible her memory was wiped after her previous visit but, what if she visited the Dark Archive in a different Impossible Girls Life? Later Clara looks at the pictures in the Dark Archive as if she is remembering past lives and thus her past life visit to the Dark Archive.
What do think fo my theories? Will we see more side effects? I think so!
