Seeing that Melanie was still with Johan, Scarlet didn't know if she was still standing and talking to him so she won't get a chance to speak with him but she didn't let that be the focus of her thought, instead, she just turned the other way and started walking after bidding Adam goodbye.
On her way home, Scarlet thought of all her schemed plans. First, she was going to meet Johan, arrange with him on how to meet his mother or he takes her to her hospital and then the last part was the most scary of them all. Thinking about it now, maybe it was the reason Melanie decided to ruin it, but who cares what happens to her?
She was going to tell Johan's mother that she has been experiencing weird stuffs and her body has been reacting abnormally and then she'll cover it up by saying that her mother doesn't know about it, just so she can think it is a secret-kind of thing. But honestly, Paige has no idea about it.
