Oh, so the witch wasn't just doing a one time thing, she's somehow actively draining Flora? Trying to take her soul/power or something entirely? Yeah definitely a "hurry" moment!
@zanonyn Since the witch has that brush full of Flora's blood, and we've seen in the past that painting at times really drains Flora's energy (life-force might be a better term), I'm sure you're right. The witch is using the brush with Flora's blood to do something magical, and a side-effect is it's literally killing Flora.
