That thing you burned up isn't important to me; it's the fluid catalytic cracking unit. It makes shoes for orphans... nice job breaking it, hero.

I should have been the one to fill your dark soul with liiiight!

Who are you? What is that? Oh, What's that? What's THAT? What is THAT?

Remember, the Aperture Science Bring Your Daughter to Work Day is the perfect time to have her tested.

There was even going to be a party for you. A big party that all your friends were invited to. I invited your best friend, the Companion Cube. Of course, he couldn't come because you murdered him. All your other friends couldn't come, either, because you don't have any other friends because of how unlikable you are. It says so right here in your personnel file: "Unlikable. Liked by no one. A bitter, unlikable loner, whose passing shall not be mourned. Shall NOT be mourned." That's exactly what it says. Very formal. Very official. It also says you were adopted, so that's funny, too.

Well, you found me. Congratulations. Was it worth it? Because despite your violent behavior, the only thing you've managed to break so far... is my heart. Maybe you could settle for that, and we'll just call it a day. I guess we both know that isn't going to happen.

This is your fault. It didn't have to be like this. I'm not kidding, now! Turn back, or I will kill you! I'm going to kill you, and all the cake is gone! You don't even care, do you? This is your last chance!

Where are we going? Are you coming back? What's that noise? Is that a gun? Do you smell something burning? Ooooohh... what's in heeeere?

While it has been a faithful companion, your Companion Cube cannot accompany you through the rest of the test. If it could talk - and the Enrichment Center takes this opportunity to remind you that it cannot - it would tell you to go on without it, because it would rather die in a fire than become a burden to you.

Your entire life has been a mathematical error... a mathematical error I'm about to correct!
