No more than 2 hot blondes alloed on the Lost island at a time.
First there was Shannon and Claire.
Then Libby showed up and Shannon got shot.
Then Libby got shot and we got Niki, but we knew that wasn't going to work out because Juliette was on the other side of the island.
Now with Niki gone the island is back to normal.
Only 2 Hot blondes on the island at a time. It's a Lost rule!
