"There were colored lights: green and red and yellow, twinkling from a tree which was, oddly, inside the room." This difference in The Giver the play and the book is very effective because in the play when he shares love for the first time for Jonas he described how much he loved Rosemary. But in the book he shares his favorite memory with Jonas, love but in christmas way.
" Then the sled, with Jonas himself upon it, began to move through the snowfall, and he understood instantly that now he was going downhill." This is really effective because you can tell that Jonas is very fast understander on everything he's receiving.
"Actually, Jonas thought, trying to re-create it in his mind, it wasn't Fiona in her entirety. It seemed to be just her hair. And just for that flickering instant." This similarity is effective in both the book and the play because you can really see the expressions and you can really see how gray and black everything is and then her hair justs turns red tells Jonas that something is going on, that maybe he is seeing beyond.
