Theory 2- The grabber has son

I think the grabber has a son and (I think he died)

Because, In the movie when Finney was sleep and woke up he said "I just wanted to look at you" and I don't know if it's just me but when he said that he lol really sad almost as if he was about to cry.

the grabber only kidnapped boys and (also all the boys he kidnapped had long hair or some-what longer ) and he was playing with Finney's hair when he first kidnapped him and that might be something that he did with his son and his son also had long hair.
