If it was a dessert smoothie (chocolate, coffee, peanut butter, etc), his love for Eddie is endless as he does not care much regarding his health, only his happiness and comfort. Likely he is trying to win him over/apologize for something. If it was a banana and fruit mix, they're comfortable together and their Father/Son roles are distinct. If it was a green smoothie, he likely is more concerned over health than happiness, indicating their relationship is strong enough that he does not have to win him over with a smoothie. Father/son #goals, as you would say.
