Let's have another look at Michael.
First he says his parents are alive, then he jumps all over Riley when we she asks about them. Later we find they died in a car crash. Did they? I only ask because we have really seen people go crazy when it comes to revenge. Scratch is the primary, but we CJ break character, Burt and Riley go off the deep end. I understand the blood lust, but looking for one person in Southerrn California with everything else going on. Michael sure goes crazy over Randy. Michael hates odd numbers in the field and he leaves his wingman. One IS an odd number, but it is sooo much worse.
Randy
He could be a good guy or a bad guy. I like the trap idea, but I also find it hard to believe Michael could make it out f the water works alone. He also yells Randy when recovering from his surgery. That is a pretty deep penetration of the subconscious to just have seen the name Randy on a techie uniform.
