If you remember back to the crazy episode where the Human VCR was recording Talia's reactions on a crystal for Kosh (When she examining the Kille's mind), and Kosh said "For Later" (or something close to that), the intention was to use that crystal to "fix" Talia, but, this is one of the very few plot points that got dropped in Babylon 5, since real world actress wanted to be "The Star" or to be released.
Reflection, surprise, terror. For the future.
I've never been sure about that 'fix' part at all. None of the images that Talia flashed on were at all positive. I've always wondered if it might not have been intended as a weapon instead. I'd hoped that JMS would clarify it in the script book intro for this episode but it didn't come up.
