whats the truth..

does samar knows the truth behind all these messages. does he know the truth behind the prism. todays episode showed as if he knows what this prism tells and what lies awaiting for them. i think he knows. thats why he is almost forsing ira to go ahead with his plans.

bt i don't understand why does he gets upset when ira decides to go away. nw he knows almost all and can find the secret himself too. why does he have to ask ira to stay and find the truth. Is he in lve with her!! Bt he does nt show it much.
