"Star Wars: Rebels" will start the second half of season 4, and fans are very excited after the trailer was released. The over two-minute trailer has many things that fans noticed, which either proved their theories or teased something interesting.

The trailer starts by giving a brief recap of seasons 1-3 and then more clues about the upcoming episodes are revealed. It shows the orphan Ezra Bridger, who is looking for a place to belong. Luckily, he is saved by Kanan and is brought with Hera and the rest of the Ghost crew. But Ezra also helps Kanan by restoring his confidence, which eventually leads to his being a Jedi.

One thing that fans noticed is the new look of Kanan. Hera said she does not like Kanan's new hair, but it appears that this has something to do with his journey as a Jedi. Fans will figure that out once the "Star Wars: Rebel" is released next month.

Kanan takes Ezra on a journey in search of his first kyber crystal, which will become one with its master creating a living symbiotic bond. But Kanan will be gone, and Ezra needs to finish learning his Jedi steps even without a teacher. He will use the teachings of Kanan and the Force to guide him. However, things are not simple since he needs to overcome suffering, pain, and maybe even death.

Ezra will do everything to fight for the people. With Kanan gone, he will stand as the new leader of the Rebels. He will use his unique Force abilities that allow him to connect to all living beings deeply.

The trailer also shows a convor bird, which may mean that Ahsoka Tano will appear again. To recall, "The Clone Wars" featured the journey of Anakin Skywalker, Ahsoka, and Obi-Wan to Mortis where they encountered three Force wielders, the Father, the Son, and the Daughter. With the appearance of the convor, it shows that it will tie back to the trio.

"Star Wars: Rebels" returns Monday, Feb. 19, on Disney XD.
