Carl ran to the museum. He didn't realize how horrible everything was without, well, evil. As stupid as that sounded, it made perfect sense in context. He pushed several people out of his way to get in screaming "LET ME IN! THE FATE OF THE WORLD AS WE KNOW IT - or, rather, I know it - IS AT STAKE!". He jumped into the time machine and pulled the lever. "Hey! You can't..." a museum security guard began to tell Carl. "...do that." he finished after Carl had gone to the past. Carl was about ready to fix Doofenshmirtz's life for the better, when a second Carl showed up.
