Notes:

Tuvok gives Kes a mind meld to teach her how to control her abilities, so Tuvok has pretty much mind melded with everyone now.

The rock is like a tracking device for the caretaker’s mate. If they find her they might find a way home! I totally believe that might happen!

There’s an Ocampan named Tanis. He explains how Voyager has gained a reputation in the region. I guess gossip travels faster than Voyager

Kes shows him her plants. Tanis explains how the Ocampa on the station live twice as long as the Ocampa on the home world, and they are much more powerful

Tennis uses his mind to contact the caretaker’s mate, Suspiria, and tell the viewers that he has bad intentions

She starts hurting everyone so Janeway zaps her. Janeway releases her and Suspiria is impressed by her mercy, but she just takes off
