Forgive me if I'm wrong, but I think Lois doesn't need much of a fake identity to go to the hospital. She could just go around, looking, and, if anyone asks, she's visiting a friend. 'Chris Nicholson. What do you mean, he's not here? Oh, I guess I came in the wrong hospital'. No reason to suspect her, unless she's caught in the act - but she'd be careful enough, wouldn't she?
Just a thought,
AnnaBtG.
