Warren Vidic
The lead scientist in the research of Altair. He is shown to be somewhat of a ruthless man. Initially, he attempts to push Desmond beyond his limits by keeping him in the Animus, only to be accosted by Lucy. Relenting slightly after Lucy's initial concerns, he is further pacified after Desmond agrees to not resist their work. He remains pushy throughout the game, chastising Desmond for wasting time at the Animus memory selection screen for delays or for walking around the room in the middle of a memory segment.
Emails accessible after the completion of a memory segment further show him to be impatient, perhaps to the point of being sloppy. His emails are written without capitalization, and he doesn't bother signing his emails. He wonders aloud to Lucy why she bothers signing hers, since it indicates the sender quite clearly in the header. On at least one occasion he loses his access badge, which Lucy finds and returns for him. He is dismissive of her calls for him to be more careful with it, replying that she should be more focussed on the Animus and their work with Desmond.
