Bill is always watching Dipper, he likes to watch Dipper sleep in the same bed with him. Bill likes it when he feeds Dipper himself with a spoon, he likes to watch, he likes Dipper's presence. He loves Dipper, he loves him madly

but why is Dipper at Bill's and not at home? Bill kidnapped Dipper to be there because he wouldn't deny his feelings, right?

Bill walks into his bedroom after a busy day where Dipper is chained by the leg to the bed. Obviously, Bill missed Dipper very much all this hour...

Bill sat down on the bed next to Dipper

Bill: Dipper! I'm home~

Bill kisses Dipper on the neck like a loving and obsessed husband
