Foster La Maison Des Amis Imaginaires Saison 0 Épisode 26

Children who create imaginary friends usually take care of them until they are 7-8 years old. Imaginary friends, left on their own after this event, continue to live in this home founded by old Madam Foster.

Some years after their son is killed in an accident, a married couple decide to adopt a child. One day a 7-year-old boy, Eli, unexpectedly arrives on their doorstep claiming to be from the adoption agency. Eli wears a suit every day and is very well-spoken for a child. He helps the adults to process their loss, which had stifled both their marriage and their toy business, and lets them embrace life again.
