Chakotay does not have his medicine bag on him when he is beamed back to Voyager. It was either on the Kazon ship or in the shuttle that exploded, yet he uses it when he is back on Voyager.
The new TR-590 Tricorder X and the redesigned type 2 phaser appear for the first time here, although how Voyager was able to procure these newer models when it was cut off from the Federation was never explained.
When Captain Janeway and Lieutenant Tuvok are on the surface of the moon and Jal Haliz tried to get them to follow him, Tuvok disagreed and then Razik was following them with Kes behind Razik. The next shot shows no sign of Razik only the Voyager crew that were searching for Chakotay.
After the initial battle with Kar, Chacotay's shuttle reports that long-range communication, lateral sensors and aft shields are off-line. However after he & Kar escape from the Kazon main vessel in the same Starfleet shuttle, the Kazon ship hits the shuttle again. This time the shuttle reports aft shields at 68% instead of destroying the shuttle.
