The situation was getting more and more chaotic, Shouki and Eijiro both didn't want to be separated. They both wanted to solve their problems without any interference from the other party. They don't need opinions or solutions from other people that are not related to their problem. They are really stubborn.
It's their selfishness and stubbornness that keeps them from realizing how much of a mess they've made. And now they are battling another alpha that has power no less than theirs.
Actually the alphas are not interested in interrupting them. However, if the damage gets bigger, then they will be called as one of the people responsible for this incident.
