Omer is rushed to St. Sebastian's, Jack passes Sayid & Nadia

After Sayid takes Eva and Sam to the bus stop, Nadia runs out of the house in a panic. We cut to St. Sebastian's Hospital where Sayid and Nadia pass by Jack in an old school Lost cross.

Omer is being wheeled into surgery with a punctured lung and internal bleeding. The doctor says that he appears to have been mugged. Sayid starts to leave to take care of the situation, but Nadia begs him to let it be and go home and wait for the kids.

Sayid visits Nadia, Omer, Sam & Evan after returning from Australia

At the start of "Sundown" we see Sayid arrive at Nadia's house in a cab, but it is quickly revealed that Nadia is married to Sayid's brother Omer and they have two kids Sam and Eva.

Sayid says that his job is traveling the country, translating oil contracts for an oil company and that's why he was in Australia. Omer runs some dry cleaning businesses and just opened a new store.

When Omer leaves to take a call, Nadia asks Sayid if he received her letters. Sayid says yes and Nadia asks why he never wrote back. The kids come into the room with the boomerangs Sayid brought them from Australia, interrupting the conversation. Eva shows Nadia the picture that Sayid was carrying on the plane as Omer looks in from the other room.

So from the start of the flash sideways, it's clear that Sayid and Nadia have feelings for each other, but what happened in their lives to make it turn out so different? How does Sayid have that photo if it was the one given to him by the CIA and ASIS unless he's lying about his work? Did he still infiltrate the terrorist cell in Australia?
