Interesting developement.
This is how a skittish Lois would handle it. Actually I have to think that the fact that Clark is Suerman is the only reason she's let him 'inside' this much already.
Someone who's been in hiding for four years is going to be extrememly careful about who she tells what to. Even if he is Superman.
Clark impatience is understandable but also it's fueled by his own personal desires in the manner and he has to realize that Lois doesn't have the emotional connection to him that he has manufactured over the years. He has to be on guard against pushing her away by being too forward.
Tank (who thinks the Daily Planet will have to think twice about hiring back anyone who takes four years to finish a story
)
