Unbeknownst to Arianna, Kyrena had been observing her through a magical mirror this entire time, taking enjoyment out of watching her suffering. And now, watching her be nursed by a wild animal, she was cackling with glee, before being struck by inspiration. Casting a spell, she enchanted the bear's milk, which passed the magic into Arianna as she drank it. And now that it was in her system, it would start to affect her, with the bear's licking triggering the first aspect of it.
Arianna, meanwhile, was completely unaware of any of this.
