Louie walks into his room.

Huey and Dewey are playing outside.

And he? He feels like he is in their way. Huey tried to calm him down, but it didn't work.
And Della? She doesn't love him either. She can't accept a son who isn't that much of a great adventurer.

He is still crying when Donald comes in to call him for dinner.
"Louie?", he asks. No reply.
"Louie?", Donald asks again.
"Go away", Louie replies again.
"Now now", Donald says. "Your brothers are already downstairs. So be a bit more kind, please. I am your uncle." Then he heads towards Louie's bed and notices he is not feeling right.
"What's wrong?", Donald asks, feeling pity for his nephew.
"N-nobody loves me", Louie whimpers.
"That's not true", Donald says. "I love you, and so do your brothers, and Uncle Scrooge."
"But mom doesn't", Louie cries. "And Dewey... I don't think that he..."
"He does", Donald says. "He is just different from you, and to me it doesn't matter, I love you all the way you are, I do raise you, but I don't dictate you to be my way. You must never forget that you are unique. Being less of an adventurer is not something that needs to be corrected. It is the way you are."
"I need a hug,", Louie whimpers.
Donald gives his nephew a strong hug.
He strokes his hair softly and rubs his shoulders.
It does not matter how hurt Louie is, he is here for him.
