This snippet is completely inspired by a fic on AO3 by Onereyofstarlight called Taken By The Light. I strongly recommend you read that first so that this one makes sense.
The loss of John affected everyone.
Even little Gordon could feel something was missing, and when Alan came along the next spring it didn't make them whole again.
They would never be whole.
Virgil spent weeks searching for his brother, unable to accept his immediately younger brother was gone. But Scott…
Scott never forgave his parents for sending John away somewhere he couldn't go, where he couldn't protect him like he'd promised.
Overnight their happy and protective oldest son changed into an angry hurt child. It didn't matter that he'd witnessed what had happened that fateful day. It didn't matter that he didn't have John's powers and could never really protect him. It didn't matter that John had gone willingly.
All that mattered was that the Jedi had stolen his brother away and his parents had given him up willingly.
Jeff and Lucy had often repeated Kreen's words to themselves, that Scott would come round in time. But as time went on he didn't become any more accepting.
Scott became more and more withdrawn from them, spending every free second outside and away from them.
And then one day Scott was gone.
