The guy was a willing participant. The scene where he turns up the one chemical was one of those "supposing" scenes. The guy who was guilty, that Mac was interogating (I am having a total brain melt here, sorry) wouldn't tell Mac what happened, so Mac was saying, "Maybe he turned up the ....(whatever chemical it was). And they showed a scene of that actually happening. So, supposedly that's what happened, but it was Mac's narrative, not the guilty guy. Were you able to follow any of that? :lol:
