I can't recall this episode, maybe I missed it or we are still lacking behind in Old Germany. BTW I love the team of NCIS, they are a pretty unusual bunch
It was a great episode. Also for those who are into "Star Trek" there were two guest stars, one who had a connection to "Enterprise" and one to "Voyager".
The cards Abby used were really large. I liked that she said using the cards helped her think.
