What if Adrien was seriously injured as Chat Noir and ended up in the ICU. Gabriel goes into despair thinking he lost the last of his family. He starts to spend every hour possible by at the hospital mumbling things that sound like a prayer apologizing for everything. When Adrien wakes up, he see his father sleeping in a chair next to his bed, messy hair, more than a little stubble and overall a mess.
Adrien mumbles a soft “Father?” waking Gabriel from his sleep. Gabriel has tears in his eyes and hugs Adrien really tightly, sobbing out of sheer joy and explains he was so harsh because he didn’t want to lose the last family he had and that Adrien meant the world to him.
