WARNING: The following article contains spoilers for "Terminus," Episode 23 of Young Justice: Outsiders, streaming now on DC Universe.

When Robin (Dick Grayson), Kid Flash (Wally West) and Aqualad decided to step out of their mentors' shadow in the first season of Young Justice, they were quickly joined by Superboy, Miss Martian and Artemis. The animated series went on to add several heroes from DC's deep roster of characters, but the core cast of the show has always centered on those six characters.

That's what made the events in Season 2's finale so tragic. The Team worked with the Justice League to stop a rash of natural disasters caused by The Reach's magnetic disruptors. The Flash and Impulse attempted to stop the final device, located at the North Pole, by racing around it at top speed to siphon its energy output. It was only after Kid Flash joined them that their combined efforts were successful, but it cost Wally his life, and he seemingly faded from existence.

Now we jump ahead a few years to Season 3 on DC Universe, and things still aren't looking too good for the heroes of Young Justice. The war to stop metahuman trafficking has escalated with Gretchen Goode, aka Granny Goodness, taking Halo as her prisoner. Granny discovered the Mother Box spirit living inside Halo is the key to unlocking the Anti-Life Equation, making her the perfect gift to her master, Darkseid.

The Team and the Outsiders launched a rescue raid to Granny Goodness' Orphanage, with the teams splitting up to accomplish the mission. While the Outsiders look for Halo, the original Young Justice roster acts as a distraction. However, Nightwing's recent time in Granny Goodness' X-Pit is having a lasting impact, causing him to experience a fever dream in the middle of battle. A surprising outcome of Nightwing's condition de-ages The Team back to their Season 1 appearances, and brings back Wally West to fight by their side.

When Nightwing is knocked down from a Parademon attack, the outstretched hand that helps him to his feet belongs to Kid Flash. Nightwing sounds just as surprised as the rest of us to see Wally, but the change in their costumes and a slight haze on the screen signals that this isn't real. However, it's still fun to listen to Wally as he zips around the battlefield, commenting on the "newbie" Artemis. Nightwing (as Robin) even references many of his signature lines from Season 1, like when he told Kid Flash and Aqualad they didn't come for a play date inside the Hall of Justice. Miss Martian even drops in a "Hello, Megan!" line for good measure.

While Kid Flash lays claim to the Justice League's Javelin as a souvenir, Robin hacks the ship to use as a weapon against their opponents. From there we jump to a fighting video game sequence in which the heroes fight along and together until the Parademons and Furies are defeated. It's here we learn Nightwing's suppressed memories  hacked The Team's psychic link, causing them to experience his fever dream together.

Nightwing is obviously embarrassed to have those thoughts displayed to his friends, but Artemis lets him know Wally is always fighting by their side. As Wally's girlfriend, Artemis is probably the only member of The Team who truly understands how deeply Nightwing misses his best friend. This is the second time Wally has returned on Young Justice: Outsiders, with the other coming when Beast Boy was almost hypnotized while wearing the Goode VR Goggles.

Fans are admittedly excited to see whether the creators behind Young Justice bring Wally West back into the fold, but with only three episodes left and plenty of storylines to wrap up, it seems unlikely at the moment. However, it's also likely not a coincidence that Kid Flash is being used in brief cameo appearances. For now, all we can do is be patient and wait for Wally to hopefully race back onto the show for the already-renewed Season 4.

New episodes of Young Justice: Outsiders premiere Tuesdays throughout the summer on DC Universe.
