This is the first canonical mention of Steel, John Irons' superhero alias.
Ally Allston may be a reference to Allison Mack, the actress who played Chloe Sullivan on Smallville and was convicted in 2021 of various crimes stemming from her involvement in a cult masquerading as a self-help group (NXIVM), for which she was a main recruiter and second only to the founder. Smallville is the only other Superman vehicle to be set primarily in the town of Smallville and the only other live-action television show centering the character.
