"Nothing grandpa, I'm fine" Faust says with a smile on his face trying to cheer up his grandpa with the best smile he got.
Faust comes over to Bella and try to hold her, to which Bella doesn't agree. She just licks Faust's hand and goes inside the house slowly. As if it's her way of saying she lost her trust in him and just licks his hands so Faust doesn't completely gets heartbroken. Its as if a way of saying we are not siblings anymore but just friends who care about one another's feelings and happiness.
Gus realizing the way Bella acted, comes and holds Faust in his chest. " let's go inside, grandpa." Faust calmly tells Gus as if he is avoiding any hugs or love from Gus as he still feels he is responsible for everything that happened and he thinks he is being hated by his family too now.
