Vulnerable Child (Harry Potter fanfic)

Orion always knew just how vulnerable his youngest was, and he'd give anything to keep Regulus safe while also allowing the boy to live the bright life he deserved. And then the attack at Hogsmede happened.

Disclaimer - I don't own Harry Potter. This is my second prompt fill for Froday's Eternal Amnesty, with me filling the second prompt from Table A - vulnerable. This is also a story for the Awareness Challenge 2022, with what I want to bring attention to is Autism with a side focus on deafness, which is the opposite of the previous story I wrote for my Silent Blackness series of which this is a remix, taking the events of Silent Despair and telling it from Orion's point of view.
