in the dark: 蒙在鼓里
I'm as much in the dark as you.

我和你一样毫不知情。
That bitch of a stripper lied to us. The father's totally in the dark.
那个脱衣舞贱人对我们说谎了。小孩父亲根本就什么都不知道。

hear me out 听我说
“ Don't interrupt, just hear me out before you start talking. ”

“不要打岔，你等我把话讲完再说。”
Okay, this seems a little creepy at first, but just hear me out.

好吧，乍听起来可能有点毛骨悚然，不过还是先听我说完吧。
