by far the dumbest housemate
 

Nicola has a basic level of understanding of what's going on at any given time, like that of a little girl
she basically repeats the thoughts of other people and whenever she tries to come up with an original thought it just makes no sense
if you opened up her head there will probably just be a potato in there

She is a witch

i wouldn't call her dumb. Self-centric and ignorant, yes, but dumb? no.

she's also insecure which makes her bitchy
although I don't think there's enough activity in her brain to successfully plot against people

what has she done or said that shows she's not dumb

well i dunno, but compared to kurt and frankie, i guess it's relative.

No thats Kirk
