It is really a great story so far. What you need to do next is to write what did Ryker and Noelle do when they heard the footsteps above them. Did they investigate or did they leave the house? Since Ryker had already told Noelle that his brother was going to try and murder her, I don't think you should send them directly upstairs to see what or who made the footsteps. You should let the story continue a little more to be more dramatic. Don't let the story be a cliche like others would do. Perhaps, they could hide and wait to see who comes down. They could also catch the brother and then call the police or even the parents. You want the story to be different and have more excite to make the reader be wowed in the end.

Freedom means having autonomy and free will. In this case, an individual who has freedom is able to act according to his own wishes, without suffering any kind of limitation, or depending on anyone. Free people live according to their own terms. This does not mean that that person may violate the laws and rules of a society, as such an offense would end the freedom that that person has access to.
In this case, we can consider that to have freedom is also to have responsibility. This responsibility prevents the freedom of one individual, limits the freedom of another individual, or harms society as a whole.
Sarcasm is an ironic or satirical remark tempered by humor. Mainly, people use it to say the opposite of what's true to make someone look or feel foolish. For example, let's say you see someone struggling to open a door and you ask them, "Do you want help?" If they reply by saying, "No thanks. I'm really enjoying the challenge," you'll know they're being sarcastic. Sarcasm is all about the context and tone of voice, which is why it works better verbally. It's something you'll know when you hear it.
