Gray Putnam

is the stranded motorist Daniel Brady rescued on his way into the office at the start of episode 2x01, "Lucky Day". Gray and Danny are at least somewhat attracted to each other.

In episode 2x03 "Sin Eater" Lau learns from Brady that he is a "Yankee" and his full name is Grayson Putnam. He works for the State Department and may be seeing Daniel Brady. We find that he is in fact seeing Danny in episode 2x05 "Wind-Up Boogeyman" and see more details in the DVD extra "Boundaries".
