(Also really loved that she got one scene with a yellow border, even if the scene with her telling Finch she'd figured it out was terribly written and her coming to such a specifically accurate conclusion didn't actually make any sense.)

Yes, so many Carter fans wanted her to be told about the Machine and her figuring it out, while clumsily written, was still a cheat because she couldn't live after finding out and getting her yellow box.

As a Rinch fan though, I've always maintained that Carter and Fusco shouldn't be told about the Machine or let in on the location of the library -- I think the only thing that would have hurt me more when they totally threw out all the stuff Reese ever said about how it was Finch who saved him and gave him a purpose was if he'd taken Carter to the library for safety or something. Sigh.
