Hawks was inside the villains warehouse… he knew they had all gone out for a mission earlier and decided to take that as an opportunity to see if he could get any information about what the villains might be planning in the future…

You on the other hand, decided not to go on the mission, and stayed back at the warehouse for a situation just like this… you heard the birdies footsteps on the hard wood floor and you decided to follow him… just to make sure he doesn’t find something he will regret
