BUT THIS IS HOW IT REALLY SHOULD HAVE ENDED
EHM: I'm sorry, Captain, but I cannot perform the surgical separation. I am a physician, and a physician must do no harm. I will not take Mister Tuvix's life against his will
Janeway: Very well, Doctor. Please step aside. I assume this is the radioisotope. Locking surgical targeting scanners onto the isotope probe. Initiating...
EHM: Actually, Captain... perhaps there is another solution
(At the Super Cafe)
Janeway: ...so we transferred the synaptic patterns of Tuvix into the holobuffer, and created a holographic body for him. Then we split the physical Tuvix back into Tuvok and Neelix, and now we have the three of them.
Batman: Hi, babe. Wanna know... my secret identity?
Janeway, Oh, shut up. In any case, it wasn't even such a big deal, we did a similar thing for Danara Pel a few days before this. He will be confined to the holodeck, of course, but he has no rank anyway, and that would be like living on permanent vacations.
Superman: Yes, you did, but... didn't her mind degrade in a week if stored that way?
Janeway: Of course not, we told her that so that she accepted going back to her body, despite the phage. Why do you think the Doctor's mind does not degrade?
Superman: And Tuvix living permanently on the holodeck... won't that be a problem for the people who want to use it?

Chaotika: HAHAHAHAHAHA!!!! At long last, Captain Proton lies helpless, with his destiny on my hands! Now, finally, I shall...
Tuvix: Oh, hi Mr. Paris. Want to sing a song?
-----------------
Janway: They will be fine.
Tuvok: That's an interesting... uniform... you are wearing, sir.
Batman: This? This is not a uniform. This is my bat suit. Because I'm Batman.
Tuvok: And why would you dress like a bat?
Batman: To strike fear in the hearts of my enemies. Duh.
Tuvok: Bats are not scary. They are tiny Chiroptera mammals. To fear bats is illogical.
Superman: And wouldn't it be a problem to abuse of the holographic tech this way? What stops you from having copies of yourselves at every ship?
Janeway: You mean, someone like the Doctor but modeled after me rather than Zimmerman? Hey, I had never thought about that...
