Rosalie is good, very good. She is a level 10 SHIELD agent and is one of the smartest people alive. She is also very good on her missions and has already worked with SHIELD's top agents, Romanoff and Barton. If you think that is all, you're wrong. Rosalie graduated high school at age 6 and college at age 10 (she also has 4 Ph.D.s). Now she is 13, and has to work with avengers, and has too meet someone she never wanted to see.
