River LIVES in the library, not only is she not dying in the library, but she's immortal now, she will live in the library forever.
In fact as information, she should potentially have all the powers which the great Intelligence had.
The Great Intelligence was pissed because he had lost a thousand battles tot he doctor.
We'd seen 3, and this was the 4th.
(I'm not counting the UNIT standalone because I haven't seen it.)
996 to go.
Which means that the Doctor in all his future Battles with the younger version of Great Intelligence has to take care to make sure that he doesn't accidentally kill the Great intelligence and that the intelligence always escapes so that he will grow old and bitter and then go to Trensalor.
Was that an 8 vs. 2 crossover Clara ran afoul of?
