Question: I understand how Michael collects things to prompt certain actions after he gets "out", but how does the diamond ring work. Each item serves a purpose. to set off the sprinkler system, etc. but how does he know in advance, the kid would steal the ring? The items were placed in the envelope to "make" things happen (getting off the bus if memory serves me correctly was the point of having the ring stolen.) In the original time line as viewed on the machine, there wouldn't have been a ring for the kid steal it, so how does he know the kid will "take the bait"?
Question: How did those newspaper articles from the future get onto the stamp? Wasn't it possible only to see the future rather than actually travel through time?
