- ―Ben Tennyson
Chapter 2: The Lonely Ghost is the second chapter of 5 Years Later.
After spending five years finding his way back to Earth from his astro-isolation, Vlad revisits his old mansion, now in custody of the state, and his laboratory underneath.

Vlad is reluctant at first, but agrees when he realizes he has nothing else left to live for.

Danny and Ben then teleport to Max’s Plumbing, and come face-to-face with Vlad.

- Since his banishment, Vlad's mansion is now under custody of the town and is off-limits to the public. His laboratory is now unkept and filled with cobwebs.
- Vlad recalls his college years with Jack and Maddie, along with his accident that gave him his ghost powers, first alluded to in the Danny Phantom episode Bitter Reunions.
- Rook calls Zak Saturday for advice on ghosts, further establishing the shared universe between Ben 10 and The Secret Saturdays, which was confirmed in the Ben 10: Omniverse episode T.G.I.S. after being hinted at in the Secret Saturdays series.
- Danny, Rook, and Ben drink smoothies, a nod to Mr. Smoothy. Danny comments on his distaste with the flavor of his, referencing the odd choices of Mr. Smoothy's menu, such as Grasshopper, Lamb and Sardine, and Chocolate and Carrot.
- Ben wears a Sumo Slammer's T-Shirt, his favorite series through the entire Ben 10 Franchise.
- The map Danny shows to Ben and Rook is the Infi-map, first shown in the Danny Phantom episode Infinite Realms.

- The panel showcasing the original ten aliens in Ben's Arsenal resembles an old popular wallpaper from the Classic Ben 10 series.
- The Orion Squad look slightly different in this Chapter from their future appearances, such as Lula having only two freckles per cheek, Chirp being much larger than he really is, and GoTro's overall shape.
