Vanessa was in her room doing nothing, it was 2:00 A.M. and then...
"AAAAAAAAAAH" Doofenshmirtz yelled from the other room.
"What's wrong dad?"
"Nothing, nothing"
"Really? It's 2 am"
"I had a strange dream about that game you were playing with your friend. Portal? Right?" Doofenshmirtz muttered the last part about Portal.
A few weeks later...
"Hay Ferb what's up" Vanessa asked.
"Nothing" Ferb raplied. Crash, Bang, Boom." I think your Father is up to something, I can hear it."
"K, bye," Vanessa left her room mumbling about her dad. "What is that" she yelled. There was a giant catipiller or something hanging from the ceiling and Doofenshmirtz was holding a Portal Gun. He didn't answer, but he pointed to a book on the table. Vanessa picked it up and looked at the title that said"Aperture Home A Portal Fan's guide to life" , Not a great title for a book." Ok, what is the thing in your hand and what is hanging from the ceiling? I am interested in evil." The last part was a lie but it needed to be said to get an answer.
"I am holding a SUPER BLACK HOLE TIME MANIPULATION INATOR. And the thing on the ceiling is the Evil Science Inator. I got the idea from a dream and didn't like the names in the book. Who would name that thing on the ceiling GLaDOS? Such a stupid name." Doofenshmirtz announced with pride. Doofenshmirtz has no regards for names, or proper explanations.
Vanessa had a bad feeling of what was to come and she thought of this while going to her friends. She also thought about what time manipulation have to do with portals.
