I believe you all know that our pupils grows in a dark ambient and contracts in a light ambient, butanother fact that influences its size is if we’re looking at something/someone we’re interested or like. All these Red Beauty scenes they were at a light ambient but their pupils are still big because thEY’RE LOOKING AT EACH OTHER!!!!!1!!11!!!
If you take a look in the last too pictures, Belle pupils are bigger than ever because that’s the part where she believes Ruby’s her friend and expects to be told the truth. Also, if you’re in pain, your pupil gets bigger too and that’s Ruby’s situation when she realizes she’ll have to lie to her
