some time in the 5th series... i think its in the 4th episode after victory of the daleks in the two parter where there is weeping angels.

River song will be in the 4th and 5th episode of doctor who called the time of ángeles and flesh and stone i cant wait either as i want to know who river song is and what she means to doctor

i saw a vista previa of the siguiente ep. at the end of the victory of the daleks nd shes in that OMG i thought she might return cos she was in silence in the biblioteca with david tennant and i was waiting to see her time with the doctor, so cant w8!
