I Expected dramatic fight over beta between brothers but i believe Shaia don't talk to his brother as well he is mad and don't wanna interact with them Hugo knows that , and Shaia is little like Juda he don't wanna be responsible of family stuff but he has to be for the happiness of his bro i guess , since they are still school kids right now creating family is not part of plot. So far
yaoi logic at this point tbh. i believe Shaia is little mad because of Hugo being in love with Theo (beta boy childhood frıend/servant) and won't provide his duty as heir. so all the things up to Shaia right now. also he might in love with Theo too at some point too. in the raws he is getting mad and posessive towards Beryl when he talk to HUgp mıstaken him up with Shaia too.
