Did Randolph intend to shoot Holland at the house?
One thing I'm still trying to figure out in this film is this: when Randolph arrives at Holland's house, he stoops down suspiciously at the end of the bed and is holding what looks like a gun (barely in camera range) and when he turns and goes "How bout we...get this party started", there's a clicking noise (right before he gets hit with the knife) that sounds like the cocking of a gun. (There's also a gun on the middle of the bed, shown during the bloody shots of Randolph, he possibly could've dropped it there, but if not wouldn't he have noticed?)
Most people seem to think he was completely tricked by Holland, but I always thought that he was planning to kill them just in case they weren't tourists after all. What do you guys think? Another possibility is that the "gun" I saw and heard was some kind of drink flask to "get the party started".
