I think EJ was sick or something. Anyhow, I assume she found out about the paternity back then, but didn't tell Stephano. Either having a different father or the traditional Soap Baby Switch. At the time he said it, I immediately assumed "paternity issue".
As to EJ's mother, she's Susan Banks, the pregnant doppelganger Stephano tried to replace Kristin Blake with back when she was supposed to marry John Black. (Stephano is always coming up with or creating dopplegangers.) Susan was an Elvis fanatic, thus EJ's name. (Once again my old Days info bank comes in handy.)
As to the real father or if there's been a baby switch, so far no clue has been given.
I think the new writers are coming up with a bunch of new stuff anyhow, so the original intention may be a moot point.
