With all the personnel changes going on, necessary as they may be, it's good to see an old friend rejoining the crew. And the Pell-Lar'ragos-Sandhurst relationship is sure going to make things more complicated (read interesting).
And yeah, I don't trust the Klingons one bit. They like to talk of alliances but we all know, the only thing they usually care about is their own honor. Better watch out for these guys.
