Episode 23 of "ReGenesis"
s02e10 The Wild and Innocent

Autopsies on two dead deer lead NorBAC to suspect that worms from parasitic eggs are responsible for a recent spike in depression-related suicides in the Southern U.S. What they can't figure out is if the parasites are coming from the deer, humans or a third source. While working on a retrovirus, Jill becomes contaminated and is forced into quarantine. Owen is charged with criminal negligence when a young girl dies after overdosing on crystal meth. David comes to his defense, arguing that Owen is predisposed to being an addict. The defense sparks a fascinating legal, scientific, and ethical argument.
