The big question is what loss is the greatest?

"Superb"
We haven't seen much of Eko since his confrontation with Henry Gale in 'Maternity Leave', but we got a pretty good sign that the island was sending him a message before he got there. In '?", the island talks both to him, and the island's original disciple, Locke, only the message that they both get will put their faith in opposite directions.
Eko has a revelatory dream where the dead (including Ana, who has just crossed over) tell him to find 'the question mark'. Eko returns to the hatch and finds that one of the people on the island he was closest too is dead, and another has been mortally wounded. Yet rather than mourn, he takes Locke with him on part of a search to about the only thing that Locke knows for certain was on the blast door map. Reluctantly, he leads him to where he thinks it is, only to find the plane that both he and Eko found for different reason early in their searches, Then (in one of the episode high points) Locke has a dream in which he is Eko, and gives them the nudge he needs to figure out where the island has been leading them. What they discovering is a bigger surprise---- another hatch, which leads to the third Dharma station we've seen---- the Pearl.
What we see in the station is an even bigger shock--- televisions and monitoring equipment as well as a series of pneumatic tubes. Searching, Eko discovers another Orientation film, this time on a videotape. This time the footage in even more mysterious. The doctor who called himself Marvin Candle, now calls himself Mark Wickman (neither of which is his real name, by the way) and reveals that the Pearl is monitoring the Swan while its participants perform an experiment.
Locke faith has been diminishing all season--- Charlie's supposed lapse, Sawyer stealing the guns from him, Henry Gale's playing with his head--- but what he sees here completely destroys him. This can be seen by many way, but the clearest demonstration occurs by two actions. When Locke and Eko first unearth the hatch, he stops Eko from going first, saying 'May I?' But when he gets a glimpse of what the Pearl is doing, he takes the map he's been slaving over for the past three episodes, sticks it in one of the tubes, and launches it to parts unknown. He doesn't need to see the orientation video to be shattered, he believes he's been tricked, and becomes the man who got on the plane in Sydney, the angry man with nothing left to live for.
Eko, on the other hand, has been rejuvenated with the faith that Locke had in Season 1. When he found the footage from the orientation film in the Bible, he dismissed it more or less as coincidence. But after what the island has shown him--- the plane that his brother landed that took him halfway around the world, it's original location leading to Locke, it's ending up in a position that illustrates the question mark that Locke found on the map, and that under it was yet another Dharma station--- all this convinces him that the island has been guiding him all along, and that this is a destiny guiding him. He knows that Locke has lost his faith, and that he must recover it in order to do 'the work that the island wanted'.
With all this, we wouldn't expect much of a flashback, but we get a couple of kickers in this one. Eko continued his impersonation of a priest while he was in Australia (we never do find out how he got there) when he was called into investigate a miracle-- a young girl who drowned, and then somehow managed to come back to life. The father of the girl prevents Eko from ever talking to her by saying that this was an act of defiance by his wife because of his belief (I'll get back to him), and Eko seems more than willing to dismiss what he has learned. But when he is about to board Oceanic 815, the girl comes up to Eko with a message from Yemi, encouraging him for what he's done, and that he will see him again. The biggest shock of all comes when the father is revealed to be Richard Malkin, the same psychic who told Claire that she couldn't give her baby up for adoption, then put her on the same flight that Eko ended up on. Clearly, the psychic knew the plane was going to crash, and that Claire and Eko had to be on it. I can guess at Eko's reason; I can't see Claire's--- yet. (Eko also runs into Libby while getting on the plane, but that's only minimally interest)
Eko may have regained his fait, but everyone else in the hatch is shattered. All Jack can do is make her comfortable, so he tells Sawyer that he needs the heroin to make her passing peaceful. While doing so, Hurley learns what has happened to Libby, and is even more shattered than we can expect. This is another blow that he will never really get over, and you can tell that just by seeing how shattered he is.
Two people die in this episode, but the biggest casualty is Locke's faith. All season he has been engaged in a power struggle with Jack over the hatch, and now it seems that Jack was right about it all along, which must be the bitterest pill of all. He tells Eko early on that it's not his hatch anymore, Henry Gale's deception has led to more death, and now it seems this island has been playing with him. Eko may have regained his faith, but Locke's cynicism is no less dangerous, and will cause the castaways to face their greatest threat to date.
