Okay, for Abby and Henry dynamic in fnaf three movie, obviously Henry looks at this weird autistic little girl who was literally possessed by his daughter, and sees a bit of his daughter, and Abby sees in him what it could've been like to grow up with a father.
But Henry also sees the kids he used to love entertaining, the ones who would ask him endless questions about Freddy's and it's colorful characters. He sees the reason why he bothered to create in the first place.
For Abby? As the guy who helped build the animatronics she knows and loves, an expert in his field who loves going on long winded tangents, and also a former children's entertainer, Henry Emily seems to her remarkably like Bill Nye the Science Guy.
