Ouch.
That pretty much sums it all up. Poor Lois... I wonder if any of the women of the family will even think about telling someone about this domestic abuse.
From my own experience, I'd tell Lois to cool it, avoid talking about Clark or Kansas, just for long enough for Sam to lose interest. After that, they can sneak. It's not like he's home that often.
But I'll wait to see what you've got planned -- y'know, it occurs to me that this might be the device to slow them down long enough to grow up, to meet again as young adults instead of teenagers, and to pick up from there... but I'll wait to see what you've got <g>
