Son of Archie and Imogene.

S3E6 - Angered by Archie’s ongoing absences from their apartment, Imogene barges down to The Button Club and posts photos of their kids to the wall, including Eric. She initially mislabels Eric as “Pete” as a test for Archie, which he passes.

ARCHIE: You're hardly in isolation. Your mother's there. The kids are there. And, by the way, you wrote the wrong name on one of those pictures. Unless you changed Eric to Pete while I was out.
IMOGENE: Ha! That was a test. Thank God you passed.
