1. Portal device
   Super button
2. Storage cube
   Emancipation grill

One of the first things that Chell obtains in the "Portal" games is none other than the portal device. She uses it to solve puzzles and get closer to the real enemy of the game: GlaDOS.

1. Terrible
   Pleasant
2. Stupid
   Crazy

The enemy GLaDOS is known for her heavily sarcastic remarks and long-winded responses, so when she's hoping that your "brief detention has been a pleasant one," she really doesn't mean it.

1. Turrets
   Cube
2. Tests
   Truth

Once again, GLaDOS is up to no good with her sarcastic remarks and responses, this time by saying that she's been "enhancing the truth" to Chell. This occurs in some of the early test chambers.

1. Cake
   Ice cream
2. Apple pie
   Destruction

GLaDOS wholeheartedly believes that she can tempt Chell with cake and encourages her to quit through most of the puzzles. But did you know that you're able to find the cake in the first Portal game?

1. Marriage
   Therapy
2. Grief
   Supportive

How nice of GLaDOS to offer you grief counseling, right? Wrong, because she's a sadistic type of machine who won't actually offer you cake or counseling, even though Chell probably needs it.

1. Returned
   Created
2. Destroyed
   Euthanized

During the 17th test chamber, GLaDOS forces Chell to destroy the weighted companion cube, which accompanied her on quite a few tests as both a helpful aid and as a potential "friend."

1. Retaliate
   Speak
2. Fight
   Scream

Although the weighted companion cube doesn't speak in the game, there's an underlying message to what GLaDOS is saying here. Is she actually worried that it may talk, and if so, what does that say about the cube itself?

1. Portal device
   Cube
2. Cake
   Lift

We should probably thank GLaDOS for giving us a lift ... to the next test chamber. But regardless, it's a reward for your efforts against this evil machine (maybe she does have a soft spot after all)?

1. Kill
   Trap
2. Lock
   Damage

GLaDOS is making fun of Chell here during one of the test chambers, essentially calling out her lack of intellect. We all know Chell isn't dumb, because she (well, you, the player!) manages to solve GLaDOS' most diabolical puzzles.

1. Defiance
   Happiness
2. Success
   Back talk

Another word for "defiance" is "resistance." So essentially, GLaDOS is saying that if you refuse to participate in the tests or rebel in any sort of way, then you're apparently going to "android hell."

1. 500
   4000
2. 10,000
   50

GLaDOS says this line during the end of test chamber 19, right before she attempts to kill Chell via a fire pit. Maybe you'll be destroyed in 4000 Kelvin temperatures, but at least the Aperture devices will be unharmed.

1. Apple
   Banana
2. Peach
   Papaya

Wheatley's introduction in "Portal 2" is basically iconic. For those of us who played the first game, it was jarring but also a lot of fun to meet a character who talked to Chell and didn't seem to wish her imminent harm.

1. Management
   Life support
2. Aperture
   Portal

Wheatley is attached to something called a management rail, which he's supposed to stay on to for dear life (literally). But luckily, after he releases himself from it, he seems to be alive and unharmed.

1. Help
   Owww
2. Nooo
   Here

When Chell uses her thermal discouragement beam on turrets, they'll reply with several phrases like "This is not good" and "You've made your point." One of the other ones is "I'm on fire, owww."

1. Speed
   Power
2. Strength
   Aim

Sometimes turrets feel sad about their friends dying, but other times, they seem to praise Chell for her efforts. In this context, a turret is complimenting Chell's aim for firing at another turret.

1. Paintings
   Turrets
2. Humans
   Fire pits

Wheatley tends to talk a lot in "Portal 2," and one of the things he rambles about is humans. He actually goes on to say "And their ... folklore. Wonderful, very colorful ..."

1. Boys
   Girls
2. Whales
   Deceased scientists

We don't know if GLaDOS is telling the truth when talking about this "Aperture Science Self-Esteem Fund for Girls," but one thing's for sure: Chell is here to escape into the real world, not donate her organs.

1. Peptic
   Amine
2. Electrolyte
   Shock

Who knows if peptic salve and adrenaline is even available at Aperture Science, but it's nice to know that GLaDOS still cares for your well-being (in the most sarcastic way possible).

1. Fire
   Smoke
2. Danger
   Dead bodies

GLaDOS is talking about "danger" here, and she means it. As in, she's not really using this element for any lab tests but purely to watch Chell suffer.

1. Fluid
   Experiment
2. Volcano
   Gas

There's a section in the game that explores the "Bring Your Daughter to Work Day" aspect that "did not end well," according to Wheatley. And one of the science projects was none other than a baking-soda volcano.

1. Nitrogen
   Burning
2. Chemical
   Neurotoxin

Wheatley is talking about the neurotoxin generator in "Portal 2." After you reach it, he also says "Not going to be able to just, you know, push it over. Have to apply some cleverness."

1. Alive
   Sad
2. Red
   Dead

The song "Still Alive" plays in the credits at the end of the first "Portal" game, and the word in the blank is "dead." Other memorable lines in the song are "Go ahead and leave me" and "I think I prefer to stay inside." Good luck getting it out of your head!

1. Angel
   Monster
2. Machine
   Reaper

The full quote is as follows: "Not in cruelty, not in wrath, The Reaper came today, An angel visited this gray path, And took the cube away." Doug was one of the scientists at Aperture.

1. Love
   Warmth
2. Pain
   Sorrow

Once again, GLaDOS messes with Chell's mind by saying that she (as a machine) can feel pain, but then gets annoyed when Chell doesn't listen to her. This aggravates GLaDOS because she has nobody else to torment.

1. ANGERED
   ANNOYED
2. MURDERED
   DESTROYED

GLaDOS has some hard feelings between her and Chell after the first game. The sadistic machine also uses the word "murdered" during her reawakening and doesn't seem to understand why Chell would do such a thing.

1. Lasers
   Neurotoxin
2. Gas
   Fire

The evil GLaDOS is once again trying to scare Chell, but this time with potentially deadly lasers. This occurs during "The Cold Boot" chapter of "Portal 2" in the first testing chamber.

1. Thermal Discouragement Beams
   Water
2. Death
   Heights

When you use your portal device to launch a turret, it will sometimes say "I'm afraid of heights." It may also yell "See you soon," "I'm flying," "Glorious freedom" and "Wheeeeeee."

1. Family
   Parents
2. Love
   Happiness

During "Portal 2," GLaDOS actually has a change of heart and fights on your side against the evil Wheatley. Who knows if Chell is actually adopted or not, but according to Wheatley, this means that she has a "lack of parents."

1. Blue
   Repulsion
2. Propulsion
   Conversion

Cave Johnson founded Aperture Science, and he gives many insightful clues toward the history of this lab. He also talks about different kinds of gel substances in the game, and one of them is called repulsion gel.

1. Basalt
   Chert
2. Moon
   Gabbro

Cave Johnson was the kind of man who did whatever he pleased, all in the name of science. And in this case, he bought a lot of moon rocks to make a gel substance, but apparently, he got pretty sick from it.

1. Argon
   Chlorine
2. Water
   Gasoline

Apparently, Mr. Johnson is talking about gasoline here. Then he says, "That's normal. We've been shooting you with an invisible laser that's supposed to turn blood into gasoline, so all that means is it's working."

1. Idiot
   Genius
2. Machine
   Robot

GLaDOS is referring to Wheatley as a "little idiot" ever since he decided to go the evil route. But despite his traps, Chell and GLaDOS still manage to work together to defeat him.

1. Brain
   Heart
2. Soul
   Head

GLaDOS claims that Chell broke her heart because in the first game, she defeats her (almost). And ever since then, GLaDOS has been giving off many passive-aggressive comments.

1. Paper bag
   Sock
2. Orange
   Potato

GLaDOS famously becomes a potato in "Portal 2," sparking many hilarious comments and one-liners. And funnily enough, once she becomes powerless as a potato, she acts like a good friend to Chell.

1. Dancing
   Singing
2. Acting
   Sleeping

The full quote by GLaDOS is "dancing is not science." This occurs in the multiplayer version of "Portal 2," where you are able to do a little dance in front of your partner (which GLaDOS absolutely hates).
