Through the training, Elena managed to get through it and official became an Angel and got their official tattoo. Also, Elena begins working with Jane and Sabina as a team for the Townsend Agency.
Elena is very smart as she graduated at the top of her class at "MIT" and is a skilled hacker. Also, Elena was very shy as she would get scared real easily and whenever she is in shocked she would throw up as she assumes things, shown that she thought yellow was her color and that the assassin was shooting at all of them. Elena does have a heart of gold and easily became best friends with Jane and Sabina. However, Elena went through a great change from that shy scientist to a strong confident Angel who would't back down from doing what's right.
