The only reason why I think we would revisit the crashed labs is because maybe there are some clues there that will tell us the where abouts of Sam. Quite possiable scenero ya know? Like we return to the Almighty Raison and then he tells us to go back to the labs where we find a bunch of clues on the where abouts of Sam. Then it will begin a long journey through the massive clonglomerate of the Vykkers industrial stronghold in hopes of finding Abe's Long Lost Mother. I like it.
And to make it even more jucy Abe and Munch end up being split apart and at the end the two find their way to Sam. Two seperate adventures in one game. Theres a bonus game for ya!
