捣乱者

1.Borrower of book - those mutilator of collections,spoiler of the symmetry of shelves,and creator of odd volume.

借书者□□是为珍藏本破坏者、书本排列次序捣乱者、零星残书者。

2.What is the use of my taking the vows and settling everything as it should be, if that marplot Hans comes and upsets it all?

(如果捣乱者汉斯过来把一切都弄糟，履行承诺，把所有东西都放到应该放有什么用呢？
