Wow, we're already into the fourth episode and the Minerva has already gone through more trouble than the Archangel did. That space battle was much more intense than the ones in SEED (Like Dominion vs. Archanagel arc), and it was just cool. I thought those Guiaz's came out of nowhere, but then again they do not matter since they get destroyed. Athrun is beginning to feel rather uncomfortable after Gilbert revealed him. Gilbert continuously smiled at him as he gets more uneasy, probably Gilbert knowing what Athrun might do. Athrun, not being one to sit down, helps the Minerva in their battle.
Rey and Neo go at it again, and it was pretty much a stalemate between both of them until the Minerva managed to heavily damage the Girty Lue. During the retreat, we see that Stellar is fond of pretty lights.
What was also good in this episode is that Meyrin (the red-headed communications officer) acknowledges Lunamaria as her sister and she, Lunamaria, Rey, and Shin go back to rest. Ironically they find Athrun there. Rey is just polite, and Lunamaria has no qualms about talking to Athrun. She seemed rather grateful and also very kind to him, harboring no prejudices (for right now). Shin however says what is expected of him, and probably says that he betrayed Zaft for Orb and is not worth talking to.
However, strangely enough I think that battle sortof blew a portion of Junius Seven with distance of Earth.
Other than that, it was a good episode, but this is the episode where two particular scenes stand out to me:
-Athrun's flashback scene showed all the people that died during the course of the first war. For some reason they also show the deaths of people he was not familiar with like Mu and Natarle. But then again, Kira probably confided with him after the war about the many lives that were close to them. It shows that Athrun is now struggling how he could fight after such events and what he can do to make a difference.
-Shin's final scene displays him angsting in his room, but I thought was the best moment of the episode was when he notices his sister's cell phone, picks it up, and listens to her answering machine, smiling lovingly as he hears her voice. It gives dimension to Shin as I think it symbolizes his reason to fight. He fights for her and his family, and perhaps it shows more of what he stands for.
I'll expect a big rescue mission to attempt to put back Junius Seven into orbit by the Joule squad. Then of course, we'll see Athrun return to the battlefield, hoping to see if he can make a difference.
