If it were possible, Harrison would have glared harder, but the human face is only capable of so much, and he'd already been pushing the outer limits. Of course Barry didn't trust him. Barry had a thousand reasons to not trust him and he knew that. But right now, he wasn't going to give the other a chance. He was going to understand, without question, and without fighting. Because he wasn't in the right mental state to do anything but fight.

"To everyone," was all he said before he moved. Even with giving Barry his blood, feeding gave him more strength than he'd ever had before. He still couldn't match Barry's speed, but now he had a fighting chance. He twisted around, seizing Barry by the collar of his shirt. He could only use the one hand because he had to open the cell with the other. If Barry tried to fight too much, Harrison was prepared to do anything that was necessary. Including knocking him out cold.
