Forum:How did Handsome Jack learn about Eridium?

I know a lot of details about the story were lost on the cutting room floor, like explanations about how Wilhelm was so easy to defeat and why you can use the New-U Stations and stuff, but I don't recall any explanations of how Handsome Jack knew Eridium would form after the Vault opened, how he could use the Eridum or how he knew what was in the Vault in the first place. 184.171.196.31 23:51, November 4, 2012 (UTC)
