This is the event when you walk in on her watching a movie, and she does a leg lock on you if you agree. It was coded poorly, so I haven't figured a way to auto-unlock it at first, but I'll fix this for 0.4.6 beta and later. Or you can just replay the game to unlock it in the meantime.
That's a bit weird. "Useless mutt" requires you to choose certain options in Lyriel's dreams, but all Cait's scenes should be unlocked.
Rae's one will require you to replay the game, it's one of a few missable scenes. Bath ride is a repeatable, so you should be able to get it, probably just didn't do it yet. The last one was coded poorly, will be fixed for v0.4.6 beta and later versions (will auto-unlock if you've seen the event).
She may understand the concept of MacGuffin in itself, but it is at least weird to her that the characters are shown to react to it with a mix of strong emotions, yet the object itself isn't shown. She's still not completely used to movies as a medium.
All on The List.
This may or may not be on The List
And no comment on that
Maybe...
