"The Glass Hand" is Ridiculous

I don't get it. I just don't get it. After all that guy had to go through to complete his 'Brain' and save humanity and find out who he is, he just gets the equivilant of a back-hand by the people whom he tried to save. Ridiculous. The guy, whose name I forget, kills all these weird alien people so he can protect his hand along with the secret it holds. He gets trapped in a building with a woman who unluckily decided to stay and work late. She falls for him in the twenty minutes she knows him (also ridiculous) and when she finds out he's a robot, boom. All feelings of love are gone and she runs home to her abusive husband who is *obviously* the better choice then a nice guy (** means sarcasm, by the way). Anyways, the guy completes his hand and kills all the rest of the aliens by pulling off their medallions which are keeping them in this time and breaking the mirror to stop them coming through. He then asks the hand to tell him where the human race is hidden, since they all disappeared in the war with said aliens, and the hand tells him that they are stored on a copper wire inside him. And, he's also a robot whom the humans made to believe that he was actually human. They guy ends up alone and sad and it just ends with him wandering off to wait until the war so he can save humanity. He reminds me of Marvin the clinically depressed robot from Hitchhiker's Guide to the Galaxy. At the end of the show, the guy probably has the same outlook on life as Marvin does.
