Alex is described as sharp, witty, and hardened from her time in foster care (children must be in order to survive). Due to the nature of her powers, she is also highly observant to her surroundings and sensitive to the needs of others. While initially shy towards most people she meets, she is generally friendly and approachable. Alex has always put the needs of others first rather than confronting her own emotional turmoil. Thus, strong negative emotions can take a great toll on her well-being.
