Currently imagining an AU where instead of having them trade Torbek to get Frost back, Mr. Witch just sends Frost into the feywild to get experimented on. Frost becoming the one possessed by The Other. Frost, who so greatly values his mind and his control of it losing control. The other's reaction to learning Frost is GONE. The Krew going into the feywild to save their friend instead of Zabilna. The Krew having to fight Frosty because he lost control. Frost's guilt after attacking his family. Oh my god
