I used the model. They are sisters. the red one's fear is Hippopotomonstrosesquippedaliophobia, or (ironically) the fear of long words. the blue one is afraid of confinement, not confined spaces. if she feels something is keeping her from moving or she is literally trapped, then she, like, freaks out. but small rooms do not cause much trouble. the red one is older, though it is widely disputed in their family, as was there, as their mom was unconscious, and no one else was there except the nurses, so we're just going on their word.
