过小溪时，她滑倒了。

What did I say about crossing streams?

都说过要避免冷热叉流了？

So later in the movie when their only option is crossing the streams, the audience recalls this rule and is as worried as the characters.

所以在电影后期， 当他们唯一的选择就是穿越溪流时，观众想起了这个规则， 和角色一样担心。

Their distance from the base of the fatal hill was but a few rods, and the steeds had been serviceable only in crossing the shallow stream.
