We just saw the gloriousness that was the Supergirl finale. This is how you do it. This is how you walk that very fine line.

And one single word from Cat Grant near the end of the episode had me covering my mouth and screaming with joy, the perfect kind of line, utterly meaningless out of context, meaning so much in context, and paid for.

And, of course, a lot of questions, including the one I know is in Kenneth Hite's mind: Is the answer to the inevitable season-ender mystery "Streaky the Supercat"?
