She could always have had him adopted off screen. He could turn up aged 18 as a link between the Brannings and the Mitchells, when he can't damage Sam's character. It'd make sense if Sam had done so and kept quiet about it, as Peggy would've gone nuts.
That or an off screen death, though I'm not sure if they'd go that far.
Totally agree with you though.
