daniel is shot..dead or not?

WOOOOOOOOOW! thats all i have to say..i just found out that daniel faraday is charles widmores son..im in complete shock. although as surprised as i am i feel like that is something that i should have known all along. its one of those things that you feel should have been so obvious from the beginning and it makes perfect sense now why she was so weird when she found out that he was the one funding daniels research. 

daniel went into the hostiles area to find his mother and he found richard instead. while he was talking to him daniel gets shot from behind and we find out it was by his mother. she did not realize who he was and when he was laying on the ground he says that she sent him back to this island knowing all along that this was going to happen to him. he tells her that he is her son and she believes him and completely regrets shooting him. i am worried because right as the episode ends it looks like he dies. he cannot die because only he knows how to save the island. i am hoping that the island will cure him and maybe they will take him to the temple place to get better.

also i wonder, where is sayid? and where are ben, locke and sun? we havent seen them in many epsiodes now!
