i think daniel found out the numbers from Desmond originally and knew this would occur. It would explain why in his diary he wrote about Desmand being hsi constant.

Remeber when Daniel was crying and he didn't know why? Maybe his conciouness was sent to that point and he started crying because of something that he remmebered or realizing he was sent back. Then he got sent back and he wouldn't remmeber why he was crying. Make sense??
