Black Hole Curiosity:

Hello, I'm rewatching Andromeda on Netflix at the moment, I last saw it about ten years ago, and I don't think I saw more than a series and a half, however I'm slightly confused. I have just got to The Banks of the Lethe' and there seems to be a lot of implication, such as the line "that thing didn't just swallow my ship, it swallowed my life", as well as the fact it is used to communicate with Dylan's fiancée, that it features the original black hole from the opening episodes, however that black hole I thought was destroyed by fort nova bombs. Would anyone know if there is any light able to be shed on this?
