@Klashikari How about "D"

Spoiler for 2.0 main quest:

D - Firefly, like every other characters we met, are tricking MC to help her. She is co-operating with "someone from other party" to fake her death in a believable way. After this, that "someone" will contact MC, pretending to know her, and ask MC for help in order to set their real plan in motion.
