The Big Bang Theory: 10 Characters You Totally Forgot Existed
2. Angela Page (The FBI Agent)
Season 4, Episode 7: The Apology Insufficiency
When Howard starts working with the FBI, Special Agent Angela Page (Eliza Dushku) questions him and his friends to validate if he's qualified. After Leonard hits on her and Sheldon lets it slip that Howard crashed a Mars rover while trying to impress a girl, Angela pulls his security clearance. When Howard learns this decision will set his work back two years, he's devastated and refuses to forgive Sheldon.
Eliza Dushku is best-known for playing the ass-kicking vampire hunter, Faith, in Buffy the Vampire Slayer, but she fits the role of a no-nonsense special agent like a glove. Even though her voice is calm and relaxed, her disciplined demeanour proves she takes her job extremely seriously, and any humour or inappropriate behaviour will be seen as a detriment to Howard.
Sadly, many viewers fail to remember Angela since her character was overshadowed by legendary astronomer, Neil Degrasse Tyson, who debuted on the show in the same episode. Many science-obsessed viewers geeked out so hard about seeing the visionary scientist, it was easy to forget about Dushku's guest appearance.
