Hank moved the wheelchair, took a disc from a bag, and placed it in the player. Soon, a video of a man singing appeared on the TV. Jimmy glanced at it; the man on the TV was Gale, the victim of that murder case. His singing was decent, but the low-quality green screen video and the lyrics in an unknown language made it amusing.
However, only three people laughed at the scene. Jimmy turned his head to look; Walter was watching the TV expressionlessly. Was his sense of humor so high? Didn't he find it funny at all?
Walter: "Hank, what's this?"
Hank: "Oh, something found in a previous case. This guy was the owner of the notebook I asked you about last time. Jimmy, I told you about it. Walter is a chemistry genius. He's the one who told me about the chemical formulas in that notebook."
Jimmy: "Well done, Walter. You helped identify a highly skilled drug maker."
Walter waved his hand, "It was just a small effort."
