It is possible Charles (or whoever) threatened Alice and Betty but I don't think Hal is completely innocent. That home movie was pretty convincing. And the shoulder injury would suggest he was the one who went after Cheryl.

I guess its possible he went after her because of the threat and because she knew too much, but most of it was Charles with the green eyes.
