well now those answers were questioned and then re-examined and blown out of proportion and then they were SAVED! (ping)
CAL is the girl it was an acronym of her name Charlotte Abigail Lux.
Donna was saved by CAL and so was the others that were in the library and the girl was being saved by the moon of the library which was a doctor moon well a virus checker. ans so that will be why the logo is on the floor in the girls room was there as she is the library as i thought.
Professor River Song as i have gathered has stolen the gun that was jacks from the TARDIS and by the fact that she whispered the Doctors Real name in his ear only followed by a remark from the doctor near her death that there is only one time that he would tell her his real name and that no one knows his name, only for her reply of “Spoilers” says to me that she and the doctor have been intimate to the point of marriage and that would seen to fit with a reason as to why she knew his real name, but the fact that the doctor met her first at The Library and that is the last time that she will see him but not the last time that he will See her but the fact that the doctor used his sonic screwdriver to SAVE her and then used it to upload her in to the data banks of CAL is just genius.
the vashta narada were still not covered as meaning showing what they are but the fact of that it makes them Even more menacing and the fact that the spoors that they are made from are able to survive the pulping of the trees of there forest and start to take revenge (witch is a dish best served tepid, not hot nor cold but its that weird temperature that is between warn and cold and it is about body temperature which is a bout 37 Degrees Celsius or 98.6 degrees Fahrenheit).
so i will be looking out for those spoilers over the next week for the next episode and i hope that the vashta narada don’t get me in the mean time as i wont be too pleased.
