That's why he asked me about my crystal, isn't it?
Fang and I... we've been through a lot together. We've been together since we were kids, after both our parents died and we were sent to the orphanage. We've been in crystal stasis together, twice now. I have this brand, a l'Cie. It hasn't faded since I got here, but if it starts to fade that means my time is starting to run out... either I figure out my new Focus and complete it or turn into a Cie'th (basically a monster). Fang's always been trying to find a way to save me, because I was too scared to turn into Ragnarok with her. So her l'Cie is burned up because she actually attempted to fulfill our Focus. Mine still looks fresh because I didn't try.
So... [...] basically, I should tell her before I either get turned into a Cie'th or we get pulled back into stasis.
