Baldur's Gate 3 II: The Urge for a Second Playthrough

Oh really? Huh, I'd never have guessed. Honestly I wouldn't have figured she could get out of the camp alive even if you let her out, given she's caged way in the back of it.

You do need to escort her out, but you gain control over her for the duration (in more or less the style of summons), depending on your party set up/items escorting her out can be pretty easy or somewhat difficult, but its not too troublesome overall
