Not that I know ... but maybe in Divnity III Rhode come back ? But I've the feeling she still stands their as "a stone statue" when Divnity III is past ... But who knows what awaits us in Divninty III ?
On 7th of february 2015 : I start a new adventure in the Divinity world of Original Sin, it's a Fantastic Freaking Fabulous Funny ... it's my All Time Favorite One !
I'm thinking Rhode will be stuck a statue. Maybe placed on a pedestal or something. Then it explodes and sends the statue flying through the air, never to land... until the final movie of the game.
Anyway, my question is when you find Dr. Needleman on top of Lovis's Tower is there anything you can do for him other than read his mind and take whatever of value out of his storage?
