Gaz's had put his cap down in order to do some excercises. The garment simply got more in the way than it helped covering from the sun. He moved on with his day, only to notice he had forgotten it.

He returned to the training grounds but it was nowhere to be seen, he guessed someone must've taken it to give it back to him, so the wild goose chase began. He asked around, yet his search was cut short as he walked to the shooting range. His cap sitting on someone else's head. Yours.

"Finders keepers, I guess."

He chuckled, walking up to your side. The cap was surely helping you more at the moment than with keeping the sun out of your eyes, so he didn't quite mind it.
