Fragment z uproszczonej wersji White Fang:
White Fang knew nothing about fire, it looked like a strange live thing to him. He moved towards it. He wanted to smell and taste this strange live thing. His nose and his tongue touched the flame at the same time and a moment later he cried in great pain and terror. Nothing had ever hurt him so much before. Gray Beaver and the other Indians
who had been watching White Fang burst out laughing.
Czy możliwe jest tutaj użycie "were watching" zamiast "had been watching"?
