Carmen is a waitress.
On the orders of the British Men of Letters, Sam and Dean Winchester visit Tomahawk, Wisconsin, to investigate the disappearance of Jarrod Hayes. After speaking to the sheriff and an eye witness, the brothers head to the local diner where Dean meets Carmen, the waitress.
Dean and Carmen spend the night together and return to the diner the following morning, where Sam awaits. Carmen goes back to work while Dean learns from Sam that their eye witness, Daryn Boston, is now missing too.
- Carmen coincidentally shares her first name with Dean's fictional girlfriend Carmen Porter whom he met in a djinn-induced fantasy world in "What Is And What Should Never Be".
- Carmen is Dean's first named sexual encounter since Ann Marie in "Black".
- Dean had previously hinted at other hook ups in "Love Hurts", as proven by a hickey.
