Kate's more than a little scary and has issues – what she did to McGee was like kicking a puppy. It was hilarious when Tony and Kate make McGee walk in front of them, staying well back.
Fornell being the mole is ridiculous – he's the FBI's version of Gibbs.
Getting hacked – the computer geniuses don't even think to pull out the power cable.
Tony and Kate undercover at the clinic were brilliant – it's worrying that they were so convincing as white trash.
Gibbs is unorthodox but gets the job done. Grabbing the son and faking Fornell's death to expose the mole, he comes off as a renegade yet stays (mostly) within the law.
Perhaps not a favourite episode but very good.
