Portal 2 - Extended Ending

Not long after Portal 2 was released, I played through the game, giddy as ever. Fun, fun, fun! Then the ending happened. A few days later, I kept thinking, "What will happen to Chell now?" My mind was filled with the possibilities. But this is what I saw.

(I would have uploaded the comic earlier, but the game hadn't been out long, and I didn't want to spoil it for anyone.)
