She is extremely paranoid sometimes, only 4 friends she has are Sunny, Ball, Muddrop, and the host (Sin-Sam). But her shyness I can't exactly blame her for, because she was nearly killed by the same terrorist 7 times, so I can see why. Other than that, she's a nice and a good competitor. Just hope she doesn't shatter, because her glass remains are known to fly up to 4 miles away from where she originally shattered.
No spoilers intended, but she actually might become a fan-favourite! The terrorist will be revealed eventually.
