Forcing an upgrade

So I got to writing and figured that first, second, and third scientists would just be one-off characters but then I realized they were making themselves into too big of a deal and were getting personalities and should probably get names. So here we go.

First scientist/ Valeri Gridenko - M - A slightly-timid man whose soft-spoken manner belies great physical strength. He has a tendency to speak to Ivan when they are alone in the lab, a tendency that Anatoli finds both creepy and kind of hilarious.

Second Scientist/ Anatoli Chicherin - M - a boisterous mathematician with a dislike for manequins, a love for slide rules and unrounded numbers, and a lust for Svetlana. Valeri finds him to be brash and poorly mannered, which isn't an inaccurate description at all.

Third Scientist/ Svetlana Lazarev - F - a buxom biologist involved in an on again/off again workplace relationship with Anatoli. Her work primarily concerns space dogs.

Oh characters who create themselves are a fun deal. I'm just worried about what I'm going to do with them in act two - probably just have the actors play differently named scientists or else swap them out for Milena and Gennady and switch other characters from act one in. Necessity can be a scientist in act two, after all.
