How do you interpret/interweave Mack having had a girlfriend for 4 years through long distance into the WillMack narrative (if you do at all) or do you just ignore it?
So many fun narrys to explore here anon! Thanks for the ask. One point of clarification I believe they were together 3 years but I totally could be wrong on this front.
First, we must look at their ages. They we're quite young when they got together (14 going on 15 for Mack) when you are still figuring your shit out. Anything you do at this age is not permanent. You live in a constant state of impermanence. Including your sexuality.
Second, they remain close! It was absolutely a healthy relationship and clearly had a basis in friendship for them to have continued to remain in contact after dating that long.
Third, bisexuality is a "real" thing. People are not just greedy (well some of us are but thats for another post). Mack could be straight and just straight up fell for Will. He could be bi. He could be gay and Ella was more friendship based.
The Ella of it all is such an interesting addition to the narry and one that should be added into fics more often imo rather than ignored.
