One thing that I didn't like about this ep was that instead of forming the Astro Megazord to destroy Ecliptor once more, the Rangers instead chose to let Alpha fire away at Ecliptor, driving him away for now. A zord fight would have turned out to be more dramatic.
However, it was cool watching Carlos come to the aid of his teammates in spite of his injury. He is certainly a true hero in this ep! I was also hoping that Andros would find his sister at the end of this ep, but then again, the fact that he was really tricked by Ecliptor into returning to KO-35 certainly adds to the suspense for later eps. And speaking about the search for Karone, I thought Andros's acting was pretty superb when he was fighting back tears while watching the video of his sister getting kidnapped; I actually felt sorry for him when I watched that particular scene.
Overall, a good episode. :-)
