Death Is the Only Answer (TV story)

Death Is the Only Answer was a mini-episode of Doctor Who broadcast as part of Doctor Who Confidential.

Plot
The Doctor has entered the TARDIS control room, happily tossing a nearly aquired fez in his hands, commenting that he has missed it and can't believe River destroyed his previous one. However, the Doctor trips and the fez lands on one of the levers while the Doctor pulls another one by accident while trying to steady himself. The fez vanishes and the Doctor notices a time portal opening on the stairs. However, he is more concerned by the lack of his fez and looks under the console.

Albert Einstein emerges from the portal with the fez on his head and a beaker of green liquid, confused as to where he is, but remembering the sound of the TARDIS engine, Einstein calls for the Doctor. The Doctor looks up and Einstein asks how his old fez (the one the Doctor was happy about) got back on his head

The Doctor is happy to see his old buddy and gives him a hug, wondering how he got in the TARDIS. Einstein explains that he has been working on his on time machine, but when he tried to turn it off, he ended up in the TARDIS. The Doctor then wonders how Albert's attempts are going. Einstein explains he burned his eyebrows off, nearly died twice and fell off a cliff; however, he believes he is quite close to perfecting it. He shows the Doctor the liqued as the Doctor uses his sonic screwdriver to examine it, saying he believes the liquid to be the key to his time machine. The Doctor tells him it is not.

Einstein then wonders how he got in the TARDIS and the Doctor explains that since Einstein is the original owner of the fez, when it hit the lever on the console, it opened a time window and brought him there. The Doctor then tells Albert not to try stealing the TARDIS (again). Einstein then tells the Doctor that he promised to return his toothbrush. However, the Doctor regretfully tells him the Daleks exterminated it last week (or century).

Einstein then goes back to asking about the liquid and asks the Doctor if it's not bionic fusion liquid. The Doctor tells Einstein that he will run some tests on it, but Einstein tells him that since it's his liquid, he will examine it and asks where his bicarbonated processing machine. The Doctor only sighs that 20th century sceintists want to do everything themselves. Albert prepares to look for his machine and calls the TARDIS "old trash". The Doctor angerily yells to Albert that the TARDIS will be around until the end of time (which it was). At the same time, the liquid in Albert's beaker spurts out and hits his face.

The Doctor then warns him not to drink it, only to find Albert has turned into a red-eyed Ood with translation sphere. He is a bit amused at first that Albert's new look is an Ood, down to every last detail. Ood Albert uses his translation sphere to repeat "Death is the only answer" as he advances on the Doctor. The Doctor tries to reach Albert's intellect within his new Ood form, but is unsucceful until he waves a yo-yo in front of him and lies that it is the power source to his time machine.

The Doctor throws a lever on the console and an energy screen goes over Albert, returning him to normal. Albert is confused and the Doctor partially explains that he went a little odd (Ood) and tells Albert to keep his fried hair as it looks "more sciencey". The Doctor drops Albert off on 18 September 1945, and leaves for another adventure; unnoticed by the Doctor, a bit of Einstein's liquid remains on the console room floor, bubbling and moving on its own.
