I still like the story so far, but I do feel that some of the dialogue is overstated in this section. Emily’s relationship with her mother should be such that they should be able to communicate without spelling everything out for each other. Dial back a bit on the dialogue, and let the subtext pull your reader in. Example:
“Just be careful.”
I knew what that last euphemism meant. “Mom!”
“Well, better safe than sorry.”

I still feel like there’s something waiting to happen here, and not something good either. Maybe I’m just paranoid…

I really like the dialogue between Emily and her mom. I love how she knew what her mom really meant.
