yesss he would. i dont think laios has many opportunities where he feels justified in being jealous and possessive. being given permission to really stew in that emotion without feeling like he's being toxic, and with the trust that its just a game and kabru will always return to him so he's doesn't get insecure, i think that would be fun for him. he would definitely indulge in ways of "marking" kabru as his mate that night, bites, hickeys...
