One thing we have to keep in mind is that we're getting things filtered through Jessica's perspective. I have heard her say things regarding the first film that I didn't really agree with, so it's possible that some of the things she's saying here either aren't intended exactly as she's saying them or they are there, but not important to the broad story . . . just elements that she feels are important to her particular character. Her statements are also somewhat vague and may refer to different things.
Take this quote for example:
"There is a little tension between the Silver Surfer and Reed," Alba said of the script, which will finally bring the legendary Marvel character to the big screen. The cosmos-roaming Silver Surfer has gained an army of loyal fans with his conflicted, complicated story line. Of the Surfer, Alba said: "He's a little good and a little bad. So it's just a matter of, 'What does Sue Storm bring the good or the bad out of that boy?'"
Well . . . yeah, the surfer is a little good and a little bad. After all he is a harbinger of doom . . . but he does have good intentions in the end. I would imagine there would be some tension between Reed and the Surfer if, for example, Reed suspects the Surfer is a harbinger of doom, but he can't get that information out of him.
