Shane and Agnes Johnson

Shane and Agnes Johnson are the brother and sister of Nick Johnson. Both of the were present at the trial, and it was noticed that Nick had a surprising number of photographs of them. Both of them noticed that Nick seemed rather out-of-character in the trial, and they themselves seem perplexed by his behavior. Neither can provide insight on the paper burning.

Shane
Shane is a well-known novelist. He describes Nick as "reclusive and eccentric but not this irrational." He also notes that Nick had seemed preoccupied lately. This had been the case for years, but had picked up lately, especially at a celebration for the success of Shane's latest book. He added that Nick didn't talk much about his research, but he thought his goals were over-ambituous.

Agnes
Agnes is some kind of theoretical physical scientist. Her specific occupation is unclear. She remarked that he can be a risk-taker, and has a talent for quick thinking. She remarked that Nick seemed unusually excited when he started at the job. She also dodged a question about Nick's history before Paville.
