It tells a story set between season two and season three and it was commissioned to promote the latter as a DC Universe exclusive. It is broken up in a two-chapter story, and the first chapter was released on January 2, 2019.
Superboy enters the Watchtower for a briefing. Already present are Batgirl, Beast Boy and Miss Martian. Superboy did not expect his ex-girlfriend to be there, and everyone senses the awkwardness of the situation. Batgirl gets to it and assigns them all to Alpha Squad. Their mission: Psimon. The criminal entered the US and passed through customs by using his powers, but he was picked up by cameras. Beast Boy thinks it wasn't very smart of him, but Miss Martian sees it for the trap it is. She assures she can deal with him, which prompts Superboy to interject and remind her of a previous bout with the telepath, which left him in a coma.
Batgirl and Beast Boy stand aside and watch it unfold and are surprised, because even after the messy breakup, they seemed to be getting closer again. They even got along great on a mission to Mars not too long before. Superboy picks up on their whispering and agitatedly hurries them all along.
Alpha Squad tracks Psimon to the Goode World Studios classic movie festival after he was spotted photobombing a guest on the 1K Wordsworth app—more evidence of a trap. They split up and look for him. Beast Boy and Miss Martian take a detour, as one of the guests is Goode World and Hello, Megan! star Sandra Stanyon. They're both hoping the show will come up in the Q&A, but it's mostly about her old movies and co-star/ex-husband Jonathan Lord. Superboy joins them and urges Megan to ask a question about Marie Logan. Sandra remembered her well, and can see a similarity with Megan. They both exclaim Marie was their mother. Sandra is pleasantly surprised, but wonders why Gar is painted green. She invites them to lunch after the session. Miss Martian thanks Superboy for helping her, which he claims he did because they are teammates. Just teammates.
Barbara scours the halls with little success until she is confronted by a random man. The man reveals himself to be Psimon, who is only visible to her. He picked her first because she can't stop him–he has diplomatic immunity from Bialya, is blocking her psychic link with Miss Martian, and can overwhelm her easily if she so much as moves.
The rest of Alpha Squad sits down with Sandra. She has heard of Marie's passing and it saddened her; the cast felt like family. Megan wishes she were there. Psimon, in the meantime, is able to trace Miss Martian and locks on to her and the rest of the Team. He transports them into her mind, which is filled with... Hello, Megan!.
- Superboy and Beast Boy familiarize themselves with their surroundings. Beast Boy is in the shape of a frog, and his ability to talk in beast move sets off alarm bells for Superboy. They quickly learn where they are when Mrs. Wheeler walks in to chastise them about their language. She calls down her daughter because her friend is here, with a frog. As Megan walks down commenting about taking care of the class frog, Superboy realizes they're trapped inside M'gann's mind.
A "torch song" is a sentimental song about lost or unrequited love.
