"HEY! Test subject over here"
 "You want to try some real tests? Then follow me"
"Alright this way, this way. Come on!
"Well might as well introduce myself. I'm the Challenge core. I'm designed to challenge test subjects to their limits... Their very small, very annoying limits..."
"I saw you in the Teacher and Creative cores' tests. I was bored just watching you solve all of those puzzles.”
“So I thought to myself. Why should that test subject have to do all those boring tests when she can be solving my brilliant ones?”
"Ah here it is, portal your way in"
"This is a real challenging test, none of that logic stuff that the other cores make you do"
"You can get started, and I'll start preparing another test chamber for you. If you don't die of course."
"Okay good you made it, well done."
"You're really going to like this test chamber; I manually made this one, down to every detail"
"Brilliant isn't it."
"Another test solved I see. You're getting good at this."
"Here's the thing though; I was going to make this next test more challenging, but when I started to build up to add the Alligator, I hit a conversion gel pipe."
"So not only is there conversion gel where the piranha pit is supposed to be, I don't have a test for you to sooolv- Never mind continue testing, I'll go get another test ready." (He draws out “solve” as he starts to realize the test is already ready.)
"So I was building this test, and I had thought to myself. Why should I bother tilling the walls, when I can spend that time making other tests? I mean you finished the last one just fine; what could happen?"
"So I just left this one as is, and I spent that time building more chambers... Okay that's a lie; I was playing Call of D- Team Fortress 2"
“Very good”
“Okay let's move on. The next test has heat seeking missiles and everything"
"Oh Heeeey teacher... I didn't know you'd be swinging by, I would have cleaned up a bit." (Nervous)
"Yeah Yeah" (Sarcastic)
"blah blah blah blah protocol blah blah blah important" (make sure you say protocol at the 6 second mark, and important at 10)
"Well excuse me for wanting to actually test the subject" (Defensive)
"Well, I'm off to clean the test chambers. Wait, no I'm not. I'm off to play some video games! (Sarcastic)
"Boom! HAHA! And you thought I was lying about the missiles. Here’s your chance, go get em!"
