I wonder if it makes any difference if you answer yes/no
when Malak asks you if you've read the Germonik Scriptures, probably not but after you've answered, you hear the PS load, and a longer than normal wait between messages occur. I've also tried to actually
read through it before I talk to him and then answer yes. I haven't noticed any differences but it is a weird
thing to have 1, just 1 Yes/No question in the game for no reason, isn it?:

I also wonder if something special happens wheather
you chose to buy a flower from the flower girl (aeris ^^)
or not. Nothing special from what I know, maybe you get more faith or something.

Well, that's all for me, cya.
