poor Dark, the rose bush reminded him of Roze, a vampiric plant that caught him in her thorny vines right after he set foot on Ashe. And lucky for him, the locals asked Valen to get rid of her since she tended to kidnap and drain them of their blood.

there are some mistakes but I'm to lazy to fix them. and Roze is that color because Dark's having a brief flashback of her.
