Portal 2 Book Ends
GLaDOS: Let's be honest. Neither one of us knows what that thing does. Just put it in the corner and I'll deal with it later.
That's how we found this thing, lying around in a corner in the Aperture Labs, and we thought you, our most prized test subject *cough*, could actually benefit from it. It might help preserve your life if you stumble upon trouble in the test chambers!
We're just assuming, but remember the books we gave you to prepare you for the test? These bookends will definitely look fancy on your bookshelf while holding the books we gave you. No need to read them, though, you'll do just fine!
Cake and grief counseling will be available at the conclusion of the test.
