You know, if he'd been given trilamide,

如果他服用了三酰胺
the unsub could have forced him to cut himself.

不明嫌犯完全可以逼迫他自残
It makes sense for a sadist with abandonment issues,

对于有被抛弃史的虐待狂这才说得通
But why didn't he finish the job?

但为什么不逼他自残至死
The victim must have gotten a chance to escape and took it.

被害人肯定找到了逃跑的机会并且行动了
But how? The trilamide kept him compliant enough to hurt himself.

怎么可能三酰胺足以让他乖乖地自残
It overcame his self-preservation instinct.

完全压制他的自卫本能
Well, then another instinct must have been stronger.

那就是说另一种本能更为强大
- Like what? - A protective one.

-比如说 -保护别人
This guy was mentally and physically compromised,

这家伙的精神和身体那么虚弱
but he still went after the unsub with everything he had.

可还是不顾一切地跟不明嫌犯搏斗
Who would he fight that hard for?

他这么拼命是为了谁
