Abnormally tenacious, Chell seemes to never give up. Ever. Chell is also highly resourceful, quick-thinking, very intelligent, strong-willed, good at creative problem-solving, and does not panic easily. She has a tendency to isolate herself and come off as rude or unlikeable because of her problems socializing, contrary to these thoughts, she is a very sweet, but lonely girl. Wheatley is never far from her, and while it's odd for her to have a constant babbling friend, but she quietly appreciates his company.
