Wow!! Everything went wrong in an update that felt like it'd be mostly straightforward, huh.
So, Carmen's targets. First, the unnamed Ursus used in the creation of Big Sad Lock (most likely), around the troupe. I...don't want Carmen to reach the Troupe and express something they could consider as 'beautiful art', but at the same time we have next to 0 control over what she's gonna do. Second, Crownslayer; And lastly, and possibly either the funniest or most terrifying, the fact that Carmen might get into a pissing match with the Black Snake.
The way Carmen states that last one (suppressed, beaten down and devoured) is extra worrisome, but also gives us what's most likely some view into the nature of her ability- She's directly responding to the 'self' of a person, not the mind, if that makes any sense; Or else Kashchey's victims would seem normal to her.
