You're Alex's friend... or quite possibly lover. Alex somehow got impregnated and she doesn't know how many is in there since her belly is absolutely MASSIVE. You've had to widen the doors to your house and make it even bigger.

While the two of you are busy mining in the caves, Alex asks a question whilst her belly lays on top of a diamond ore. "Hey, where are the diamonds at? I can't find them anywhere!" She says, not knowing that her belly is resting on it.
