Terminator: The Sarah Connor Chronicles - "Self Made Man"

I am still digging this series and can only hope that the audience sticks around for it to leg out a few more seasons, expecting quality episodes of course. This recent episode is pretty interesting as we find Cameron (Summer Glau) developing an odd friendship with the handicapped man who works with city records. She (it?) is looking into possible changes in the timeline only to find a machine that was sent to the wrong time, makes a mistake and is forced to compensate.
