Luberto Headcanon #30
Both can get possessive and protective of the other when the other is either scared or gets hurt, you would think the one that enters a feral like state when seeing the other hurt would be Alberto, no it's Luca he gets down and all fours and hisses at anyone attempting to come towards Alberto, most of it comes from the panic and guilt over what happened when Ercole shot harpoons at Alberto and capturing him in the net.
He only allows himself or Massimo around Alberto when his hurt, and growls at anyone else attempting to come closer, which includes Giulia and his parents. He has to be at the others side, so the first person Alberto would see will be him.
When Luca is hurt, Alberto holds him tight but does ask for help, tears running down his face, sure he gets the urge to hold the other closer and want to help him himself, but he knows he wouldn't be that good at bandaging a wound so he reluctantly hands Luca over to the ones he know can help Massimo and Luca's parents. He tends to stay with Luca but mostly on the edge or near enough to the door, scared that he will get in anyone else's way, and just waits for Luca to wake up.
(both Massimo and Luca's parents have tried coaxing Alberto closer, they succeed half of the time, before he reverts back and slinks to the door, that happens when Luca makes a noise of pain. And yes Alberto blames himself for whatever happens with Luca, even if he wasn't there during whatever caused the other to get hurt)
