Need help with a movie script

[Ghostface]

The plot revolves around a human male, 21 yrs old, and an female alien with a human "facade" The movie begins with the male talking about his life and then "everything changed" ala an intro (the males intro, female follows first but that I'm still working on). He is walking across the street when the female alien is running from sweeper agents sent by the US Government to terminate their creation, at this point he is saved by her (on accident) from being hit by a car. She grabs him and runs off intending to "learn" from him about human identity, culture etc but changes her mind because when he explains some things to her, concepts like being nice, understanding etc. I'm having troubling make this sound real and believable and not coming across as weird. That's all I've got done so far. The male guy writing him is no problem. But the female alien is hard to write. She's mysterious, has trouble grasping human concepts, and "seemingly devoid of emotion" but really just having trouble understanding the concept of emotion. Like when she's happy she doesn't understand or at the time know what it means. I need help with her badly.
