S06E06

When Ray leaves his car for the coffeemeeting with Teresa, making an interesting call about a woman that has to be shut down, it turns out to be a Mercedes whitout a licenseplate. He appears untracable. 

Near the end of the episode, Teresa is lifting but first time a fast car drives trough without even slowing down. It's also the same type of Mercedes, this time with licenseplate (one cannot really read it). Maybe there's a passenger, but that's also not very clear. If Haffner is in the car, would he have recognised Lisbon - and if so, why didn't he stop?

Another issue: since the spy-woman that was to bug the CBI knew her killer had a tattoo on his shoulder, it seems that she must have had sexual intercourse at least once with her Tyger. Bertram might have been attractive to her, maybe McAllister but definetely not Smith.

Last question: what did Partrigde knew so he had to die? I don't see it, very unclear stuff.
