what she means:
elise is only romanceable if you choose the prince, and elliot is only romanceable if you choose the princess. it's unfair that lionhead shoved heteronormativity upon us, when typically they are good with things like equality in their games. it would have been nice to be given the option in the beginning of the game, just like how we were given the option to be male or female. elliot or elise. sigh, it was pretty unnecessary and i cry myself to sleep every night wishing my princess could marry elise in canon.
