If you talk to Jessie in the tunnels before entering the second reactor in Midgar, she says something like "I'm sorry. The ID scan problem on the train was all my fault. I tried to make yours special, but I failed."
If I understand this line correctly, it means that Jessie was actually dumb enough to express her feelings for Cloud by making him a "special" fake ID, with extra decorations and stuff that weren't supposed to be there, rather than a plain, inconspicuous-looking fake ID. If this is what the line means, then it was a good joke in the script, completely wasted on crappy, unclear delivery post-translation.
Or do you guys think this line means something else?
