精选对白：
Katherine:Please understand...
Rose:You have just signed our death sentence.
Katherine:Better you die than I.
Elena:Rose and Trevor spent the last 500 years running because you used them. Trevor just got killed.
Katherine:Never thought he would have lasted that long.
Elena:You don't even care that you ruined their lives.
Katherine:I was looking out for myself,Elena. I will always look our for myself. If you're smart,you'll do the same.

脱掉字幕：
1.You don't even care that... 你竟然都不在意......
表示对别人冷漠的行为不能理解时就可以用这句话，意为“你竟然都不在意......”，care用于口语中表示“关心，在意”，相当于词组care about。而向别人表示自己并不关心某事时就可以直接说I don't care.
2.I was looking out for myself. 我要替自己着想。
我们把总是替自己着想的人称作“自私自利的人”，评价这样的人我们可以说He is always looking out for himself.
look out for意为“当心，提防”，所以look out for oneself就表示“为某人自己着想”。
