David at Collinwood and David talking with Sam Evans are two different kids. Sam says afterwards to Maggie that David's a nice kid, and I agree with Sam – and then I remember that David is the child who stubbornly and unpleasantly insists, in the face of all evidence, that he did not remove the bleeder valve from of his Father's car. If David ever decided that Sam was mean to Burke Devlin, Sam wouldn't think David was a nice kid anymore.
I'm really appreciating Dana Elcar’s performance in this round of watching, and wishing his role had continued to be as good as it is at the moment. Maybe it's hard to keep the sheriff smart when the monsters start buzzing around his head – but if I remember correctly, the sheriff in the 1991 series was pretty smart. Or else I just really liked the guy who played him.
