Sub-Evil Boy’s frantic scrabblings

I saw The Cronichles of Narnia last night and I enjoyed it. There was one flaw that was incredibly silly of them to have missed. In the begining you see lucy give Mr.Tummnes the hankercheif. A few sences later, Mr.Beaver give her the same hankie she gave Mr.Tummness wich makes sense. Then at the very end of the movie, Mr. Tummness give Lucy the hankie that she already got from Mr.Beaver. What the heck is going on???????? I can’t beleive nobody at disney saw that. I’m thuroghly anoghed. If anyone has any solutions, please leaave them as a comment on this post. Thanks!
