Sorry for not clarifying my question in the title, but wanted to prevent spoilers...
Maybe I just forgot how it happened (it's late in my timezone and I'm a bit tired), or something strange happened: I restored my saved game from yesterday, when Abe's head was still on the moon. Then I got into Hugh's room using the eye and the spoon bending thing, Max got his body parts removed, and after a little experimenting I now have his hand back. In between all this, I did some moon-earth traveling and vice versa (because I didn't know what to do).
OK, to make the long story short - I just went to Sybil's office and there's Abe's head on the sofa?!
Did I miss something? How did it get there? Or did I simply forget? Maybe I was distracted during a key scene (I'm watching Nickelodeon on TV additionally, "Real Monsters" is on :D)...
So, am I going crazy or was this some kind of "bug"? Anybody?
