I can see why you liked this episode, Krystal. It did have more character building, especially for Kurdy, who until now, we really didn't know that much about.
I'm not sure about Jeremiah though, he seems to be a little manic; the way he ranted at Kurdy, then later said it was only a way of keeping him from coming with him. Kurdy had no intention of going with Jeremiah anyway, he was much to wrapped up in his memories and the puzzle of his mother and fathers's deaths. Jeremiah really believed what he said to Kurdy, he would have killed the skinheads if Kurdy hadn't stopped him.
Did you notice that the equipment that the vaccine was made with had a large "Vs" on it -- more Valhalla Sector references -- yet Jeremiah didn't ask anything about Valhalla Sector!
Character building is good, but Jeremiah wants to solve the puzzle of Valhalla Sector, and it drives him more than anything else, so it makes no sense that he didn't ask about it.
