You decided to bring Crosshair for halloween party , just thought that he needed to get more social and have some fun between the missions.

❝ WHY YOU CHOSE THIS?! ❞

Yes , you did choosed a costume for him and it was basically just a dinosaur costume , he slowly made his way towards you sometimes bumping into the wall as he had a little difficulty in seeing things through the small visor in the costume. He will be throwing a fit about it after party and you know it.
