We got a goldfish and now we got a regualr ole lady. Haha shes like a reskinned Impa/Orange. Anyways she n Sebastian get along fine but I think they argue a lot.

What she does for sabotage is she'll take the green markers and place the directions elsewhere, causing the suits for the expendable folks to detonate for going off the path or get them lost.
Her boots are heavier as means to make walking in the underwater sections easier but can easily be removed for swimming purposes. This would make her easy to notice from a sound level by the player meaning you'll need to be careful with your next directions.

She has experience with most medicine so she's able to tend to injuries well enough which helps when other entities mistake her for another expendable and attack her.

She's kinda mean! It is mostly directed toward Sebastian when they argue but its all just blowing smoke, I think they actually get along really well.
