When playing BG3 with a friend, we each took control over our own custom character and our +1. My friend had Shadowheart, and he'd often get to places she couldn't reach, or simply forget to regain control over her.

So, we'd often play forgetting she even existed on our first playthrough, and whenever we'd ask ourselves "Where's Shadowheart?", we'd humorously respond: "Shadow WHO?".

Her story ends being blasted by a dragon as everyone else run's to safety.
