The "Arrow" episode titled "Green Arrow and the Canaries" is setting up a new superhero spinoff.

“Arrow” is ending, but a new era is beginning. Tuesday’s episode of The CW drama is actually a backdoor pilot for a potential spinoff, “Green Arrow and the Canaries.” The episode will pick up in 2040 with Mia, Dinah Drake and Laurel Lance suiting up to save the city in the future.

Mia Is Different: The trailer has already indicated that Mia (Katherine McNamara) is living a much less traumatic life. Instead of being trained by Nyssa and raised in secret, she has grown up in the public eye as the daughter of the greatest hero alive. That changes everything.

Mia is a happy-go-lucky socialite who doesn’t want to commit to a desk job at Smoak Tech alongside her brother William (Ben Lewis). She’ll need her memories of her old life back before she agrees to help Laurel (Katie Cassidy) and Dinah (Juliana Harkavy).

Star City Is Safe: Sounds crazy, right? Well, Oliver certainly didn’t fail his city. After Crisis, Star City becomes one of the safest places in the world. However, there are forces looming who want to destroy that reputation.

No Present Day: Fans will have to wait until next week’s series finale to see how everyone has been affected by “Crisis on Infinite Earths.” The entire hour will be dedicated to the 2040 storyline.

Laurel and Dinah Aren’t Old: They are their 2020 selves who both ended up in 2040 separately. One planned her trip. The other very much did not.

Huntress’ Daughter: Helena Bertinelli/The Huntress is not in the spinoff pilot, but her daughter Bianca Bertinelli (Raigan Harris) appears. She plays a big part in the episode.

Dinah Sings: Fans were very excited when they saw a photo of Dinah singing in this episode. The Black Canary has some serious pipes that she gets to show off briefly in “Arrow” Season 8, episode 9.

No Oliver: His presence looms large, but the original Green Arrow is not in the penultimate episode of the series.

“Green Arrow and the Canaries” airs Tuesday at 8 p.m. EST on The CW.
