Colin & Mary
Despite her feelings for Jim, Mary wasn't blind to the fact that she was attracted to Colin as well. It was partly physical. He was so handsome and had such a nice physique. Of all the people on the island though, she felt like Colin understood where she came from the most. His life and upbringing had been similar.
So when she saw him, she always made a point to say hello. Mary came up behind him and gently put her hand on his shoulder. "Are you enjoying your evening?"
