What if... and bear with me on this... what if SE made it like adlibs. You'll be going through your quest dialogue when the NPC asks "So what did you find out while gallivanting around Western La Noscea?" and then a text box opens that says:

Please type out what you remember happening:
And then you can type whatever you want. If I wanted my character to be a pirate, I would type "Yarrr... I be seein' some nasty things in yonder fields!"

And it doesn't matter what you type because the NPC will continue talking like he/she assumed you said what they wanted to hear. In fact, there probably won't be a submit button for the text box, it'll just cut you off at some point.
