Any predictions what her "condition" is? Maybe some kind of anti-magic aura since she was able to repulse the prince's unconscious female-repulsing-magic for herself and those nearby.
Is obvious she either have magic herself or block the magic effects around her and that's why he doesn't make her sick and the glamour around the witch vanished showing to everybody her aged real look.
The two panels at the bottom of page seven is a mood. Prince is all "I'm gonna kill you", and Renald just clapped back "Bring it bitch." like it was nothing <3
