First and foremost: Isn't democracy a beautiful thing :D
Second: I think that Blondie is so disassociated and repressed, that hugging him would at first short-circuit him, and then absolutely wreck him. Like, he would just start crying. Ugly sobs.
However(!), he would (with the messy help from Tuco imo) gradually accept that he also has needs and there's nothing wrong with that. And (maybe-slowly-carefully) he would start letting Tuco (and other people) into his heart.
He adopts a kitten. He helps Marisol escape. At the end of the day, he always comes back to Tuco.
He accepts that he is capable of love, as much as he needs it given to him.
He nuzzles to Tuco's soft chest and falls asleep, not guarding with one of his ears open for the first time in years. One of his hands is still petting the kitten.
