GH-Don't u think Dr. Devlin is a bit overly interested in Nik's head case?

He very well could be on Helena's payroll! I think he knows what Jerry gave Nikolas before and that it is in fact responsible for his condition. The pill he gave him is probably the true counter agent Robin and Patrick needed before to fix him. He must be the guy that Jerry has been speaking to on the phone and who knows, maybe he was driving the night Sam was hit and he did it and is getting close to find out is she remembers.
