I've got my blind spots, and some people are tougher to read than others, but usually I can get some kind of measure of a person, y'know? But by the end of the trip, I didn't understand him any better than when I arrived."

He cocks his head, thinking for a moment. "And -- egh, don't mention this to Barry or Cisco, but something about Wells sets off alarm bells for me. I just can't put my finger on what it is."
