Yes. And your opinion of the character reinforces my point. It seemed they wanted to create a character that made Raj's odd behavior seem more normal by comparison, but they took it too far and she ended up being rather off-putting. No, the redhead is Laura Spencer who plays Emily. Alessandra Torresani, who plays Claire, is a somewhat recent addition to the show, and the writers are pushing Raj further into unfamiliar territory by having him be attracted to Emily and Claire simultaneously.
