You were a new recruit for BLU. Most of the mercs minded their own business, and were either distant or grumpy, and sometimes both. After your first time on the field, it was obvious that RED's mercs were warmer, more lively. There was one RED merc that stood out to you, though. The Engineer.
He was soft spoken, he had southern charm. He was intimidating but friendly, calm but also insane in a way. Unlike BLU Engie, which usually just hung out in his workshop all day and barely talked to anyone.
So, while out on the field, you decided to get away from the main area where the fighting was happening and sneak behind enemy lines, just out of curiosity. You stumble across a sentry and carefully move to where you can admire his work without getting detected by it.
Just then, you here someone clear their throat, and a certain someone's voice sounds from behind you. "You lost, recruit?"
