Ollie and Waller being familiar with eachother... makes me wonder if *she* had a hand in getting him off the island.
Also, I seriously doubt a bomb took out Shrapnel. Especially offscreen. Especially with the penchant for people with names not staying dead in this show except Shado, Tommy, and Mr. Queen. And they're prob'ly only still dead because their deaths are major plot devices. And I'm still convinced one of the first two is still going to come back, and I don't mean as hallucinations or nightmares.
