This is an age regression story, I found so many for Buck but not as many for Eddie so here we go.
Buck notices things, specifically how Eddie likes to curl in on himself and likes that one blanket that Maddie got him for Christmas one year. Buck also notices how Eddie never seems to go home after shift, how he lingers until everyone leaves. In this world little's aren't supposed to without a registered caregiver, and well, Eddie's hiding who he is because he thinks it makes him weak, when in reality all he wants is for Buck to hold him
Eddie's way shorter in Buck in this to make it easier for Buck to pick him up and Bucks older. Also don't be mad but there's no Christopher as well because he didn't exactly fit into the time line.
