剧情简介：Brannen猛地想到谁才是真正的杀人凶手，在没有通知Booth的情况下闯到疑犯家中，碰巧对方正在销毁物证，Brennan不得不拔枪射击，跟踪狂Oliver和Booth随后赶到……

【台词片段】

Bones: Oliver, I understand you’re here out of a misguided concern for my safety but I apparently don't read people very well and you could be in some kind of psychotic collusion with Ken so I am going to ask to you go over there and apply pressure to his wound until the police get here. Do you understand?
Oliver: Okay. Okay. Did he kill Cleo?
Booth: Yeah, he killed Cleo.
Oliver: Okay then I'm down with him bleeding to death.
Booth: If that guy bleeds to death, Bones will go on trial for attempted murder. You don't want that now do you?
Oliver: I wouldn't want that.
Booth: Besides applying pressure that can be very painful.

【台词翻译】

Bones: Oliver，我能够理解你到这儿来完全是出于对我的人生安全不必要的关心，不过显然我看人不准，说不定你某种程度在精神上支持Ken，所以我命令你到他那边去按住他的伤口等警察来。你听明白了么？
Oliver: 好吧，好吧。是他杀了Cleo么？
Booth: 没错，是他杀的。
Oliver: 好吧。那让他流血致死的话我可没意见。
Booth: 如果那家伙流血致死的话，Bones就会因为蓄意谋杀的罪名而被告上法庭。你不想她落得这种下场是吧？
Oliver: 这我可不想。
Booth: 顺带一说你去压住他伤口的话，他会很痛的。

【口语讲解】

be down with

be down with有两种意思，一种是表示因什么而病倒，比方He's down with a high fever——他因为高烧而倒下了——还蛮直译的。

另一种就是这个段落里所用到的，“means you completely agree with doing whatever is asked or wanted finished”用于表示完全同意、双手赞成，之前就有看过一部电影叫做Down with Love，想来其实可以双关的用法哦。
