Meanwhile, the recently released episode on His Dark Materials introduced Texan aeronaut Lee Scoresby and armored bear Iorek Byrnison -0 the two beloved characters in Philip Pullman's trilogy. In the book, The Golden Compass, Lee knew Iorek a bit, but the series suggests the two are much closer than previously thought.

In episode 4, Lee told his daemon Hester that the bear saved their lives, and he's now coming to the northern port of Trollesund to help Iorek, as his armor has been stolen and being held in indentured servitude. In the books, Lee bids his time Trollesund, waiting for new expeditions. But in the series, he appeared to be close to Iorek, and it's exciting to see how their history will unfold.

Meanwhile, the introduction of these two characters made most fans really happy. Fans took to Twitter and praised the recently released episode, with one fan saying episode for was a great introduction for Lee and Iorek. Another user said that His Dark Materials got even better now that Lee arrives in the series.
