FTR HE WOULD HAVE ABSOLUTELY TOLD HER AND ROSE THERE WERE DRAGONS NOT TOO LONG AFTER THEIR INTROS the rundown would've been like "they're powerful and sentient and dream controllers of some kind and one is definitely malevolent and has sea drake minions while one is friendly but trapped"

i've just been very slow but yeah you can handwave her having that background knowledge going in to the void mission!
