Tom could have kicked himself if he wasn't currently walking. Sometimes the alternate dimensions, aliens and what-not meant he put his foot in his mouth. This was one such occasion.

"Ziggy and Jack are twins." Tom clarified as he tried to dig himself out of the hole he just threw himself in. He could have kicked Tommy too for the amused little smile the older Anthean had. "I meant our youngest daughter."

Hopefully that would kill this line of questioning before he got truly backed into a corner.
