lf superhero fic?

The fic is on ao3, unfinished, sbi-focused I think, ur average superhero fic where tommy works at a superhero tower(i think) & sbi are like the big superheroes, also tommy is an avian but its a secret and only a few people know. the author put in an authors notes they weren't planning on revealing tommy being an avian to anyone in the outline, which i think was the last chapter. 20k+ words. The only chapter I can remember was somewhat near the end where sbi + others have a cookout, maybe in celebration of Tommy's birthday? idk, im reaching. Pretty certain niki is involved too.
