Angie may seem a bit critical at times, but only to help Derek work at his full potential. Angie is very knowledgeable and can usually take control of the situation, but occasionally gets rather childish and emotional. When she does focus, she is able to think ahead and looks for the best possible situations.
At the end of Trauma Center: Under the Knife 2, a relationship between Angie and Derek is implied.
Angie is voiced by Wendee Lee.
At eight years old, Angie's father, Kenneth Blackwell, abandoned his family without providing a reason why. His absence greatly affected her.
Angie went to high school with Molly Swift and Michael Kobourne.
Angie's interest in her father's work inspired her to work in the field of medicine.
During the events of Under the Knife, it was revealed that Angie was a potential candidate to become a Sinner for Delphi's experimentation, and Kenneth ended up working for Delphi in exchange for Angie's freedom.
Angie is of German descent.
- In 'Infiltration', Angie says she has studied Aikido.
- In "Dark Gospel," it is revealed Angie was kidnapped by Delphi to ensure Kenneth's cooperation.
- Angie strongly denies her feelings for Derek, but she isn't as focused when something happens to him.
- In Second Opinion, Angie continuously panics when Derek was infected with GUILT.
- In Under the Knife 2, Angie starts carelessly dropping equipment when Derek was at Hope Hospital during his depression.
- In Under the Knife 2, Tyler asked Derek and Angie if they were in a relationship, and Angie strongly denied.
- There is no proof of a real relationship, but Angie seems to care about Derek.
- Angie makes a cameo appearance in Trauma Center: New Blood with Dr. Stiles in the fourth Episode of the seventh Chapter and in the fourth Challenge mission. In the first appearance she and Derek were just back from Caduceus; in the second one they make Markus and Valerie test their simulations.
- It should be noted that the game states Derek and Angie are from Caduceus Japan, even in the English version, despite the English versions of the other games stating they are from Caduceus USA. This is likely because New Blood takes place in the USA in both versions.
