They meet again at dinner where she is now dating Raj.
Emily reveals she's okay with it and her friends love the story. In "The Anything Can Happen Recurrence", Raj and Howard watch the gore-fest "House of 1000 Corpses" because Emily wants to watch it with Raj.
Emily suggests that if he'll show her his pierced belly button, he can see all her tattoos. In the next episode, "The Status Quo Combustion", the gang was happy about how serious his relationship with Emily has gotten, though she did not appear in the episode.
In "The Hook-up Reverberation", Penny and Leonard meet Emily for the first time and she treats Penny rather coldly.
At Bernadette's suggestion, Penny stops by Emily's office to do her sales pitch in front of a real doctor.
Upon meeting Emily, Howard recognizes her because he had a blind date with Emily sometime near 2009 before he met Bernadette.
She also admits that it turns her on, so Raj immediately starts it so they can watch it.
In "The Gorilla Dissolution", Raj and Sheldon find Emily at the movies with another guy. The guy was her tattoo artist who had been asking her out for weeks and she did so just to end the obligation.
Also while Stuart and Howard are fighting, she tells Raj that she is having a great time. In "The Anxiety Optimization", Howard starts a game called "Emily or Cinnamon" where people have to guess whether statements Raj has made are for the woman he loves or the dog he loves. In "The Intimacy Acceleration", Emily gets Raj, Leonard, and Amy to go to an event escape room where puzzles have to be solved to exit the room.
Unfortunately, the puzzles don't prove to be very challenging to the four, who all have advanced degrees, and they get out in only six minutes.
