lol mate, I didn't do that... I wish I did though.

I am assuming the person used adobe premiere though.
And the Flay x Yzak thing just kinda turned up when Flay got recruited for ZAFT by Rau I guess...
It's strange though, since the only thing Yzak said to Flay was "sit down", and it wasn't in a very romantic way if you know what I mean.
