"When that other Clark told me that he and Superman were the same," her voice was lowered considerably, "and we came out of fiction, or however that works, I watched everything I could get my hands on and read what I could. It's not..." she paused and started over. "It wasn't a picnic seeing an outside, objective view of how I treated my partner while fawning over Superman. I never realized how much I'd hurt him. How much it must've hurt Superman -- Kal-El -- to know I loved him but treated his other self like dirt at times."
Lois wouldn't use the word humbling out loud, but if she admitted it deep down, it had been somewhat of a slap in the face. A good wake up call.
