Omega!mack resting by the side banished outside by felicia because "you're a guest mack you don't need to help." So he's just watching his mate-alpha!will playing with the children outside so free and loud and happy that it makes his chest clench in want. He wants that for them, he wants a family, he wants will to hold his children, he wants to be pregnant with will's children!
So basically a serious case of baby fever.
When they get home he all but jumps will and now normally will is more than happy to go along with him but he's curious what's gotten mack so worked up and mack admits he wants children and will doesn't think he's serious at first then he realized that he really actually is so he reminds him they have a new season soon
Now mack is sulking and refusing to talk to him even though it IS logical and mack would absolutely hate and be miserable having to sit out even a singular game let alone all the games because will is absolutely never going to let his pregnant omega anywhere near the ice. With no other options he finally relents and asks #thealpha gc about it and is offended when they all simultaneously tell him a variation of "brother just fuck him are you stupid."
