Not much is known about her, but Melissa clearly loved Patrick, and he loved her. When the three astronauts returned from their mission to Mars and attended an honor party, Melissa had no knowledge that Patrick was engaged in a making out session with Marcy and later engaged in a sexual one-night stand with her and her sister. Much later, on the last night of the ten-day quarantine the astronauts were subjected to after their return to Earth, Melissa proceeded to have sex with Patrick after getting him away from the rest of the world by going to his country lodge/cabin, but Patrick didn't feel up to it. She tried to assure him that everything was alright, and that she would "do all the work".
The morning after, Patrick awakens to find her body bloody and that he had fathered another hybrid child, killing his fiancée in the process. He then attempts to commit suicide, but later regenerates due to his alien half regenerating his destroyed head.
Patrick Ross is the fiance of Melissa. He truly loved Melissa. They have sex intercourse after Patrick became an alien hybrid. Patrick is shocked about Melissa's death and their hybrid son. This causes Patrick to try and commit suicide. However, his alien half regenerates his head and takes control.
She doesn't really have a relationship with her and Patrick's son. After being impregnated by Patrick, she immediately gives birth and dies shortly after. After Patrick regenerates his head, Patrick hides him in a remote shed on family property to cocoon, awaiting his rebirth as an adult.
