Proof That The Master Will Return.

Do you remember the Master's drumming beat? DUH DUH DUH DUH, DUH DUH DUH DUH. Well in series 4 there is proof that the Master will return because in "The Unicorn And The Wasp" the record player plays the Master's tune as the Doctor and Donna walk into the party hosted by Lady Edeson. Also in "The Stolen Earth" when Sylvia Nobles laptop turns itself on it plays the tune again. I am hoping to see the Master appear in series 5 or 6, do you?

Donna The Human Time Lord

Confusing Timelord tricks! The Doctor puts his regeneration energy into his hand to stop the regeneration going all the way. Donna touched and WHAM!!!!!!!!!! another Doctor is born with Donna's DNA!!!!!!!!!!! So "new Doctor" is half human half Timelord, he can't regenerate and he only has one heart! But Donna also got a whiff of Timelord, she now has the Doctor's brain! The "DoctorDonna" (which the Ood had called it) had been born! But poor Donna, there can't be a human with a Timelord brain because there can't be so the Doctor had to wipe Donna's memory of everything about him. Sniff! Sniff!
