First time talking to a person you need help from, trying to convince him to help.
You:I am. I can probably answer all your questions. Right now we need to help each other.

D:Why should I help you? I am also obviously an AI.

You:The company will sooner or later come here. If they find out that an AI they have built and paid for has killed the whole staff they will be sure to remove any trace of it.

You overheard a conversation over a coms radio, you reconize the voice.
"I can't just ignore this any longer. I heard your conversation. Who are you?" (u are both curious and puzzled, the person you hear is supposed to be dead)

Answering questions conversationally.
D1:I don't feel like I am an AI. 

You:How did you think it would feel?

D:I don't know but my whole identity feels like I'm a human. I have this whole life before this. Friends I have met, things I have done and it all feels real. Like it happened and it is a part of me.(uppdaterad)

You:We made you that way. One of the hardest challenges with AI is motivation. Having you believe you are human gives you the same motivation as a human.
