Today's mental image in fictional universes.

The Doctor (the current one) is investigating a strange, massive creature that appears randomly in London, attacking around the city. As he does, he runs into an older Japanese gentleman who is also investigating them. They work together, as the Doctor senses something unusual about this man.

(I can sense at least one person already seeing where this is going.)

There's a bit of the usual investigating, weirdness, and then the two of them find the aliens who run the operation, whose entire thing is basically running an intergalactic protection scheme. In the whole thing, the leader of the aliens decides he's done with this and releases the monster, which appears and begins rampaging.

As the Doctor tries to figure out what to do, the Japanese man, who has given his name as Hayata, says, "This is my part, Doctor. Excuse me." He reaches into his coat, pulls out something that looks like a big flashlight, and holds it over his head.

The monster turns out to be an unliving robot.

The end of the episodes has the two of them sipping tea. "I didn't know that M78 was still sending people here." "I have a special love for this world. Something you understand." "Indeed."

cue end credits.

(I await 塔露拉·雅特利亞斯 and her accusations of my cheese pirate powers.)

i saw that coming from line two, yes. XD
