The evidence of years of
hideous experimentation that
used company employees as
guinea pigs.

We cannot know how many were
forced to become subjects, but
based on the evidence, no less

some of them taken deliberately

safe.

Where the Doctor is now I do not know.
But considering the recent rapid growth
of the Umbrella Corporation, I cannot imagine
that this research is continuing.
