"Hermione has hurt a fly and she's hurt people before," Reid pointed out. "She's also capable of every murder that she's being accused of." He quietened down when Derek glared at him.
"She didn't do this."
"You don't have any proof that she didn't," JJ said. "She has no alibi."
"She does," Derek muttered. "She's been with me for every single one of these murders. We were trying to keep the relationship secret so we could prove that it didn't affect our work." He looked at his teammates. "She's innocent."
