Cadet Catherine's other ingestion

I noticed that Cadet Catherine had only 1 other ingestion before she became Largum's lunch. I liked the idea that she would have been very competent with criminals but maybe a little less experienced with nature.

So she steps in the wrong place when her, Missy, and Emily chase a fleeing alien through the marshes of Planet Rien. Needless to say they lost track of the fugitive as they had to chase after Catherine afterwards.
