Motherboard.

Either nobody noticed it or the post was deleted, but at the start of season 2 why did Motherboard suddenly was able to move her head around? I mean look at season one her head (except for her mouth and eyes) her head remained completely still. Then when I watched the 2nd season premire she was able to move her head around. First she had to move her eyes to look around, now she can move her whole head. Can anyone explain why she was suddenly able to move her head? Also the portals looks slightly different. At the first season they didn't reflect images like a mirror, now they do.
