Awesome episode, I enjoyed the part where the Impulse flew thru the tunnel, and I thought it was pretty cool when Shinn had to throw the mobile suit to blow up the Lohegrin cannon.
I think Athrun feels bad because the two people who are very close to him(Kira and Cagalli), oppose killing...

What the hell is up with EAF forces? There all a bunch of bad guys that want you to blow their brains out now, I mean seriously, its like their leadership has gotten ten times worse than in Gundam SEED.
