In Season 2, fans get acquainted with Kaz's emotional backstory. When he was a kid, he and his brother Jordie were diagnosed with the firepox plague. Presumed to be dying soon, they were both tossed on a corpse boat and left to die. But, miraculously, Kaz (Freddy Carter) survived. The sad news, though, was that Jordie didn't.

Jordie soon died on the boat from the plague. This left Kaz to stay on the ship and be the only one alive, surrounded by the touch of his brother the other dead people.

In fact, the way he eventually was able to leave the boat was by using his brother's body as a human raft.

Now, we see that he wears gloves in order to not feel the touch of anyone. He was left too disturbed and distraught by the boat incident to feel others ever again.

Jordie, played by actor Tommy Rodger, made his first appearance in the Season 2 backstories with Kaz. He starred in a total of six episodes this season. The Kaz and Jordie scenes are some of the most emotional moments of the season.
