It was probably a testament to the number of strange situations that they had been in that Gibbs and his team didn't panic when people who looked just like them except for the fact that they were wearing clothes that seemed to have come straight from a fantasy novel and carrying wands appeared out of nowhere. They did raise their firearms the instant the other team raised their wands though.
"Polyjuice?" the wand wielding Ziva asked.
"Possible, but if so why would they be dressed completely differently and using guns instead of wands? That, and their arrival didn't resemble Apparition or Portkey." the wand wielding Gibbs asked.
"This area is magically unstable much like that area that is called the Bermuda Triangle. There have been reports of doppelganger sightings dating back centuries. It is possible that they are doubles from another universe that have traveled here, or we have traveled to their universe." the wand wielding McGee said.

It was at that time that Ducky broke the standoff by showing up rather late, both in the Coroner's van and on a magic carpet. It was obvious that there was still a job to be done and since there was only one body, it fell to one of the teams to do it. Ducky would be examining the corpse soon, and while he yelled at Jimmy Palmer for his abysmal sense of direction before he did so, both teams paired off simultaneously deciding to see exactly how alike their counterparts were.
