Martha

Martha is a Caltech science or humanities graduate student/employee who seemed to be very interested in Sheldon. She is good friends with Abby and appeared in the episode "The Psychic Vortex" (S03E12).
==Character Information==
As Leonard and Howard are both off on a double date with Penny and Bernadette, Raj feels lonely, and suggests to Sheldon that they go out and have some fun. After much persuasion and actually giving away his Green Lantern lantern, Sheldon agrees to go with Raj. At the University Mixer, they meet Abby and Martha, where Martha instantly became interested in Sheldon's limited edition Green Lantern lantern and Green lantern power ring|power ring. All four of them head back to Sheldon's apartment, where they are seen playing Rock Band.
Raj yet again is interested in going out with Abby, but she will only agree to hang out with him if Martha can come along. Raj bribes Sheldon with his Incredible Hulk hands signed by creator Stan Lee. Martha and Sheldon engage in conversation, where she reveals her interest in Edwin Abbott's novella Flatland seemingly to engage Sheldon intellectually. As Sheldon states it's getting late and he has to go to bed, it is seen Martha suspects that she can go with him by saying, "Okay.". Sheldon shocks her by saying: "Goodnight puny human!" in his Hulk voice.
As Abby and Raj are getting busy in the living room, Martha makes her escape to Sheldon's bedroom, asking if she could hang out there for a while probably hoping for coitus. Sheldon accepts actually letting someone into his room, and immediately leaves saying "I'll go sleep in Leonard's room" surprising his visitor. Martha has not been seen since.
==Trivia==
*She is one of the few women to be attracted to Sheldon, the others being Amy and Ramona Nowitzki. Possibly Kathy O'Brien.
