''It all started because I was curious. Curious what would happen if I killed them. "I don't like this," I told myself. "I'm just doing this because I HAVE to know what happens." Ha ha ha... What an excuse! You of all people must know how liberating it is to act this way. At least we're better than those sickos that stand around and WATCH it happen... Those pathetic people that want to see it, but are too weak to do it themselves. I bet someone like that's watching right now, aren't they...?''

This is reference to the people who are watching letsplays instead of playing games on their own.

''Then I woke up. Like it was all just a bad dream. I was back at the garden. Back at my "save point."... Again and again, I brought myself to the edge of death... But as long as I was determined to live... I could go back... When I saw you in the RUINS, I didn't recognize you. I thought I could frighten you, then steal your SOUL. I failed. And when I tried to load my save file... It didn't work.''

This indicates that Flowey actually couldn't perform Reset like Chara (genocide ending) or Frisk (at any time). He was able to undo his actions only by reloading save point. Of course Flowey looses this power when his save is overriten by Frisk arrival to Underground.
