They always say that the story of Harry Potter is really about Hermione and her two deadwood sidekicks, but Harry and Ron certainly have their own shining moments. Harry's brain is actually quite sharp; it only took a slight hint from Hagrid for him to figure out that they should follow the spiders.
Hermione was rather opposed when Harry made this decision. After all, it was a bit too unreliable, especially when she saw the spiders heading toward the Forbidden Forest.
However, neither Ron nor Ye Feng objected. Although Hermione felt it was rather sketchy, she didn't push the matter further. Besides, with Ye Feng around, they had a certain level of security even deep within the Forbidden Forest. In the end, Hermione went along with them, though she walked rather close to Ye Feng the whole way.
