Been listening to Swain's interaction lines...
...and I was wondering if anyone else really got the vibe of the Heart from the Dishonored games, the way he/it reveals secrets. And it's not just THAT they both do it, but the very vague manner of the revealed secrets and the way the lines are delivered, that really made me notice the similarities.
Makes me wonder if that was part of the inspiration for Swain's new direction. Considering the origins of the heart (spoilery), it wouldn't surprise me.
