4. Laura Spencer: Then
When audiences met Emily Sweeney in season seven, played by Laura Spencer, they’d watched Raj go through many phases with women. The guy who once couldn’t utter a word was now a man about town. He was already dating Lucy when Emily came into the picture. She was willing to wait, which worked for a minute, but then Raj dumped her for yet another woman, Claire. They picked back up after that, but in the end, audiences had only 17 episodes with Emily.
