I am sorry I tried reviewing the video several times but I just cannot figure out, why there is a 3rd Lilah alert at 1:30 min of the Scope video. Maybe I am too tired at this point but I do not really see that part which calls for third Lilah Alert.
Was it because first calling greeting(); created "3" variable with name person so our second calling of that function makes it read the first calling?

Basically, there are three parts being called.
greeting(); This initiates the greeting() function, which asks to alert(person); which is Lilah
alert(person); Since the greeting() function just ran, next is this, asking to alert the variable, person. As this is outside the function, it stands alone, and will come back with George.
greeting(); Lastly, the greeting() function is called one more time. Like before, it runs the same code. As the variable for person INSIDE the function is Lilah, Lilah will be the name called.
These will fire in this order, which is why you will see Lilah, George, then Lilah again. Hope this helps out. :)
Edit: forgot to put this an an answer. :)
