Stop Me Before I Hug Again - S1-E13
Character mistake: In Brian's "Laws I Have Broken Since Joining FBI" list, item #30 misspells the word "recorded" - "30) Recoreded NFL Game Without Consent." He'd only have that knowledge if he was using NZT, and if he was, he wouldn't make a mistake like that.
Factual error: When discussing a recent search of a suspect's home, Hill Harper says "we got his hard drives", but pulls a computer power supply out of a bag. Hard drives are significantly smaller and don't have a bundle of wires coming out the back of them.
Brian Finch: You remember a lot more than you think you do. Every experience you've ever had, every idea that came to you in the shower and then slipped away while you were brushing your teeth... it's all there for the taking.
