Scientist silver.

After many years, Silver has been promoted to the high rank of scientists. But at the cost of her previous joyful self being a now lesser version. Instead of letting others give suggestions, she sweeps them away and dose ot her way. Also prone to outbursts and talking down rookies for their mistakes before attempting to "fix" their act. Best, keep a distance away when she bursts out. (might add more soon as i rushed this one a bit)
