So...I'm assuming that line means she would've gone after injured players, but since she was also injured here, she .targeted...herself? I wonder if her target was based on RNG or what and she just got really unlucky. Lost our assassin, but I guess that trait would've been an obvious liability later in the game anyway.
ETA: also reading the wiki, really odd that this species was a villager since they're considered allies of the yeerks...guess this might be another game where role names don't mean much (other than obvious villains, who may have covers?)
