This implied doing something she would dread to be discovered in.
后面部分she would dread to be discovered in 整个是something的定语从句，可是我的困惑在于后面的定语从句的成分剖析搞不懂：
1）dread在这里是及物动词吗？若是及物动词，dread的宾语应该是 to be discovered in 还是 指代前面先行词的something的省略的关系代词that呢？
2) 为何句末有一个介词in, 他的宾语在什么地方呢？
3）应该是她害怕事情被发现，而不是害怕她本人被发现。所以，麻烦老师详细解说一下后面定语从句成分剖析，特别是dread的宾语和in的宾语？
to be discovered in - 不定式被动语态吧？ 应该是something to be discovered in 吗?
4) 为何不是 This implied doing something she would dread FOR IT to be discovered in. ?
This implied doing something she would dread to be discovered in.
=
This implied doing something that she would dread to be discovered in.
把something还原到定语从句中，则是
...she would dread to be discovered .
