While from the Start Captain Burns wanted Shinra to show him if he got what it takes we saw that this Eps the Most and the willpower to beat Me as he says mostly,the emotional reasons behind their actions run deep since the start of the series and Since they were Kids,its WHO THEY ARE!
It is what shaped them and WILL shape their Life and its conclusions.
While some Cuts felt Not so much Sakuga-filled and junky at times although small,it is still fair to say this fight deserved The highest animation possible but..it was still GREAT!the Story makes it All better!
All this time Burns prayed for nothing,hence his reasons were pure FAITH and it is known by this time that the reason he sides with the White-clad is because he wants to Push Shinra and Make him realize in his words:(Beware the Worlds fire Shinra!it is greater than you think!)that Strength is the only thing that matters and only thing that He will Need beside other elements to suceed in his Ideal of Becoming a HERO and saving EVERYTHING and Everyone..Burns wants Shinra to do just THAT!hence the beautiful conclusion of this emotionally driven and high Stakes Fight pays off!
