Why would Earth-2 Lois (I know it's not really her but still) call Earth-1 Lois a city whore? And expect that to get a rise out of Martha? Lois is one of the least whore-y characters in the DCU. It would be tough to find a woman in the DCU more committed to their guy. And Martha loves Lois, maybe not as much as Lana, but except when Chuck Austen is writing Martha has been nothing but supportive of her D-in-Law.
