One line of dialogue got my attention and now all I can think about is...

But you didn't have to cut me up
Make out like it never happened and that we were no team
And I don't even need your sword
But you treat me like a traitor and that feels so rough
No you didn't have to stoop so low
Collect Gast's records, kill my friends and then burn my village
I guess that you don't feel that though
Now you're not the Sephiroth that I used to know

Now you're not the Sephiroth that I used to know
Now you're not the Sephiroth that I used to know
