The next test looked simple enough. Climb up to the ledge, shoot a portal at another tilted ledge, and shoot a portal directly under you, and you get shot to a ledge right above you. Sadly, Rarity was having problems figuring that out.
"Um, not to be rude, but you are taking an awfully long time, and I would like to try." Fluttershy said.
"No! I've got it."
Ten minutes later.
"Cmon Rarity, I want to get to the surprise already!" Pinkie whined.
"No, I told you I've got it!"
Twenty minutes later.
Twilight yanked the portal gun out of Rarity's hoof, and completed the test in under ten seconds.
"Oh. Yes, I knew that..." Rarity said and followed Twilight.
"Your friend is a bit on the stupid side." GLaDOS stated.
"Shut up!"
"She's ugly too." Rarity immediately stopped.
"What did you say?"
"U-G-L-Y you ain't got no alibi you ugly!" Rarity looked like she was about to faint.
"Isn't that a song?" Twilight asked but nopony answered.
"Well, do you want to know what I think?" Rarity asked GLaDOS.
"No."
"I think that you are a lousy, good for nothing jerk, who is mean to others because she has no life or friends. If I remember correctly, you deleted your only friend. In fact, you are just making all of those things up to get on our bad side! Well i'm not falling for it, so now you have another pony who wants you dead. So good job." Rarity told her.
"She's my new favorite pony." Wheatly said. Rarity smiled.
"Apply cool water to burned area." Rainbow joked.
"This calls for a: Rarity just dissed GLaDOS party!" Pinkie cheered.
"Haha, GLaDOS is like an apple tree that just got bucked in the face!" Applejack told them.
"ALL OF YOU SHUT UP!" GLaDOS roared.
"Good job girls! You made GLaDOS lose it." Twilight told them.
"Please... Just continue on to the next test chamber for your surprise." GLaDOS told them.
"Okie doki loki!" Pinkie said and skipped through the door, and the others followed. As they entered the next room, the ceiling opened up, and a pony fell from it. A light orange pony with a black mane.
"Well, this is awkward." Wheatly said.
"Who is that?" Fluttershy asked him.
"DUH! It's Chell!" Pinkie answered for him.
"Yes, what the pink one said." Wheatly confirmed.
"I foud her sneaking around the old testing chambers. I guess she just really likes testing." GLaDOS said, making Chell frown.
"Well, at least we have a professional tester here now." Twilight said, and Chell face-hoofed.
"Before we continue testing, I think Wheatly has something to say to Chell." Fluttershy said.
"What?"
"You know, at the end of Portal 2, you said that if you ever see her again, you would apologize." Pinkie told him.
"Oh."
"Yea."
"Right now?"
"YES!"
"Well i'm sorry, but I feel bloody stupid."
"Well i'm sure no one likes admitting that they went crazy, but i'm sure it will all work out."
"That isn't helping!" Wheatly told the pink pony. Chell tapped her hoof on the floor impatiently. "All right fine. I'm sorry. I'm sorry I was mean, and monstrous, and I was just like HER. I am truly sorry."
"Awww, thank you for finally opening up to us!" Fluttershy congratulated him.
"Chell, do you accept his apology?" Applejack asked. The light orange pony nodded.
"Good, now that we are all friends again, it's time to complete this test. So if you don't mind..."
"Yea, yea hold your... something, GLaDOS." Pinkie said. "Let's go, everypony and... whatever Wheatly is!"
