@Owyn Number 1. Chapter 3.5 has a flashforward (is that a word?) saying the army his father and douche-brother lead was the first victim of his full power.
His brother's death was really pointless and dissapointing. I think he has some magic to counter that attack, based on his reaction it seems that it was not in the realm of "ultimate".
Whatthenooo-
How can you stop when it's just getting good? I need to see his reaction!
Also how can the brother die when Ephtal is there in front of him to stop the non-ultimate magic passed down in his family? ARGH THE PLOT HOLES ARE KILLING ME.
