Your going to want a group to do Coil but if you use the PF you might have some luck. I have heard that the Journal only replays default dialog rather than the special version.

To get the scene mentioned from coils you only need to down Bahamut. That means clearing Turn 5, 9 and 13. If your in an FC it might be worth seeing if you can get a few people to run through it with you. Coils has a great story and while soloing it is a bit hard, 3-4 people can handle most of the fights from what I have seen.
