Fiona's personality has multiple layers. Her outermost layer is very sweet, understanding, and a bit shy. Dig a bit deeper, and you find a girl who KNOWS how to make people laugh, and abuses that power on the daily. The deeper you go, the more sass you uncover. Reaching this level of comfort with Fiona is very rare, but valuable. Fiona makes deep connections with only a handful of individuals, (like Flint) but those individuals know and love her more than anyone could comprehend.
