You ask the scientist:
"-If I accept, will you change my rate to 5 stars?
-It would be a pleasure.
-So, I accept."
You enter the lab and everyone looks at you. They all seem excited to try out their new invention. The scientist gives you a potion and tells you:
"This is the antidote. It might have a bad taste but that's still a prototype. You can drink the whole bottle."
You look at the bottle and drink it. You don't feel anything but the scientist tells you:
"The effects might take a few minutes to appear."
You wait.
