In the intro sequence there are three people in the HTC, the virus guy who is arrested at the end, the woman who you save at the end, and a scientist sitting where the woman is standing. He isn't in the ending and doesn't seem to be present at all. Is this just a continuity error/unsolved mystery :p?

I never took my eyes off the girl long enough to notice before. Have to try and beat the game again to see.

I know the guy who installs the virus is arrested, but there's a third character working with the woman at the beginning, it almost looks like he has mechanical hands or something. He seems completely absent in the ending.
