I didn't. Not really. I had a locked up memory unit that the UNSC put in storage because they didn't think anything important was inside it, and there was no way to get it open again.

[Your fault. Rigged it so it was one-way.]

If someone gave you a locked box and said that something really valuable was inside it, they promised, but you couldn't open it up to be sure of it, would you believe them?
