As fans continue the countdown to the final episodes of Star Wars Rebels, with the back half of the fourth and final season debuting February 19 on Disney XD, new details have surfaced that present some massive spoilers for the final episodes. It has already been confirmed that Ian McDiarmind reprises his role as The Emperor in the final episodes, although little else about the back half of this final season has been revealed. The track listings for the Season 4 musical score reveals what could be a massive spoiler, so if you're averse to spoilers for the last episodes, stop reading now.

Disney XD and LucasFilm revealed last April that Season 4 will be the final season of Star Wars Rebels, with the first half of the season debuting in mid-October. The final seven episodes will air over a three-week stretch, with back-to-back episodes airing on February 19 and February 26, with the three-episode, 90-minute series finale airing on March 5. While there is still much that hasn't been revealed about the plot quite yet, some of the tracks from the musical score were revealed, including Hera at the Wall, Sabine Sees Ezra and the track that reveals a potentially huge spoiler, Kanan's End.

Disney XD and LucasFilm haven't commented on this musical score track, but it seems that Kanan (Freddie Prinze Jr.) will ultimately meet his maker. With the arrival of The Emperor in the final episodes, it's possible that he is the one who kills Kanan, but that's only a theory. There is also no indication as to where in these final seven episodes Kanan's possible death may actually take place. This also comes just after Star Wars Rebels showrunner/executive producer Dave Filoni shared a new photo on Twitter, showing Hera (Tiya Sircar) glancing at Kanan from a distance, which could possibly be foreshadowing his death.

With the arrival of The Emperor, it seems likely that the series could end just before the events the first Star Wars movie, A New Hope. It's possible that there may also be some crossover with the 2016 Star Wars spin-off Rogue One: A Star Wars Story, which is set in the same timeline between the last prequel movie, Revenge of the Sith, and the start of the original trilogy with A New Hope. While Forest Whitaker returned to voice Saw Gerrera in Star Wars Rebels, it was confirmed this past fall that Rogue One villain Director Krennic (Ben Mendelsohn) will not return for the animated series.

There have been rumors that the conclusion of Star Wars Rebels could lead to the announcement of a new animated series within the Star Wars universe. With Star Wars Rebels winding down, there is no indication when a new series may be announced quite yet. It's worth noting that there will be no Star Wars Celebration this year, with the convention returning in 2019.
