Welcome back, Quentin! Quentin left Defiance over a year ago after discovering that his mother Pilar was still alive. Pilar suffered from bipolar disorder, which is untreatable in 2047 due to the lack of medication. Rafe sent her away to a Votan monastery after he discovered her attempting to poison the children one morning. Rafe almost killed her right there, but it was Nicky Riordon who suggested that the Votan monks in Mendocino might be able to treat her. Though if what Quentin is saying is true, it didn't work.
