User blog comment:Beastie101/Does Lucy have Depression?/@comment-24200891-20170513192621

I think Lucy is so grim because she tries to cover her insecurities. Other theory of mine is she has problems with expressing emotions because she's a preterm baby with underdeveloped organism. Her nerve system doesn't work right, so she has atypical emotional reactions. Other effect of this is her pale skin since she was born.
