The Yellow one

As he looked at the Concoctions remembered what they were meant to do and trying to think which one would be best to get his revenge, his eyes focused on the yellow one. Mmm this one might do, it will make them addicted to whatever I mix into it, just the smell of what I put in there should draw them to it, and maybe it will give me control over them if I pick the right substance, he thought looking it over.

Now how will I get Emily to take this? She will never take anything I try and give her. I wonder can I get access to her water going into her apartment if so I could make something to mix it with that and then any water going into her apartment will have it so she will be exposed to it all the time, I planned for it to be drank but maybe just getting it on her skin might have some affect. Well only way to find out. He thought of this as he looked over the yellow liquid. Now what should I mix into it what will be best?
