(Scientist #2)Outspoken and Impatient. Pete is a man of action, he says what he thinks and acts impusively, for a scientist.
Pete talks a lot, he thinks out loud and works to get what he wants, his impatient behavior is rather unusual for a scientist. He can't seem to get tired or bored, always finding something interesting to study.
Like Angie, he has a stolen portal gun and Long-fall boots "stolen" from Aperture science and a white cotton lab coat.
Peter Johnson has always been a mathematical genius and a lover of physics, he has been in the army after graduating and before joining Aperture Science, which explains his fitness, for a scientist. He worked for Aperture until he put himself, along with another scientist friend, Angie, in suspended animation, waking up a year later.
