In Faith's world the flowering plants did indeed run faster than the grasses to get away from the magic fluddy.
Nothing is ever going change that believe of him/her. Remember, if Faith ever changed that believe, he/she will burn for ever and ever (in his/her mind).
Hold the Press. It was scientifically discovered that the ferns were created on the same day as the flowering plants. Ferns were created early in the morning, while flowering plants were created in the afternoon, just before sunset. Thus flowering plants were waaaay younger than ferns and therefore could run faster away from the magic fluddy than ferns could. Remember the scientific discovery of genetic entropy and all that. Science is great, isn't it?
