This is the first time that Lois admits the way she feels for Clark.
While trying to convince Lois to take the elevator rather than the stairs, Clark says, "Statistically, this is the safer way to travel." In Superman: The Movie, Superman tells Lois that when it comes to flying, "Statistically speaking of course, it's still the safest way to travel." In Superman Returns, Superman also says (in reference to flying), "Statistically speaking, it's still the safest way to travel."
This episode has a similar premise to the Season Five episode "Mercy", where a masked villain kidnapped Lionel Luthor and Martha Kent to play his 'game'. However, the two villains' motives and methods were very different.
Jimmy lied about his parents and said they are successful people when in reality they are not. Lionel Luthor did the same with his parents. Both of them did so to fit in.
When Clark and Lois are discussing Lois's answer to "Do you love him", she says she slipped the sensor off her finger while the jeweler wasn't looking, thus leading to her lie not registering. Just before Clark saves her from the chair however, you can see the sensor on her right hand, meaning she was lying about the fact she slipped the sensor off.
