What does "now" mean in this case?
Answer from a Native speaker
"Now" is still being used as an adverb here. However when it is used like this, in conversation, its purpose is to draw attention to a particular statement or point. So simply, "now" is there to introduce or give emphasis to what you are saying. Ex: Now, where did I put my hat? Ex: Now, my first thought was to run away.
