[spoiler] Bloomberg's key

[rikkles]

So I killed all the raiders before I went to get B's key, went back up to the first floor, and the dialog option stills says "I didn't find anything".
What am I missing?
The only possible reason this could have happened is that I already triggered once this option earlier before finding the key. But I'd be surprised if this is a bug.

You need to retrieve the key card from Bloomberg's room. It's in his locker (that you use his key to unlock).
