Getting Near the End

Well, here's a puzzle. At the Fair, in a long-ish scene Wilbur is awarded a medal for being so radiant. For his people, it's the greatest moment of their lives. Wilbur himself is proud and happy. This takes place in the judges' booth in front of the grandstand.
Charlotte, meanwhile, is back in Wilbur's pen, being too weak to move. She's created her egg sac and will soon die. But she can hear what's going on at the medal ceremony over the Fair Ground loudspeaker.
When things calm down, Wilbur and Charlotte are alone in the pen. Wilbur is beside himself with agony at the thought of Charlotte not returning to the Zuckerman barn with him. She tells him to settle down. 
With the people soon returning to pack up for him, Wilbur has to act quickly. He gets Templeton, the rat, to climb up and snip the egg sac from its mooring on the ceiling and bring it to Wilbur. Wilbur will carry the sac home in his mouth, having already learned from Charlotte that the sac is waterproof and strong.
Mouth firmly closed, all he can do to say good-bye as he's loaded onto the truck is wink to Charlotte. All she can do is whisper a weak good-bye. Soon the Fair Ground will is deserted. Charlotte dies alone.
The puzzle is how to stage it. If we see Charlotte and only hear the loudspeaker, we don't see much action. If we see the scene in the judges' booth--which is full of important plot elements involving mostly the human characters--how do we sense Charlotte's fading vigil over her last hours. Could we see both at the same time somehow? Maybe it's two scenes--in the novel, White gives them a chapter each. I imagine, however, that the action at the grandstand and silence and stillness of Charlotte will make for a powerful juxtaposition. 
Of course, the matter of designing the egg sac, and showing Templeton climb up to get it, and showing Wilbur put it into his mouth--well, the theatre pros will take care of all that. Somehow.
