It was such a ridiculous deus ex machina, but my heart skipped approximately nine thousand beats at the mere sight of Kellerman. I have never been more in love with a television character. Moreso when he was evil, but I'll take what I can get. As for what he did to Sara, he did sort of redeem himself by offering up a lot of evidence at the trial in season two, so I get it even if it required some suspension of disbelief. In summary... KELLERMAN HAVE MY BABIES I BEG YOU.
