Atropine



Atropine is a drug used commonly to treat bradycardia, or low heart rate, and aids in counteracting overdoses of other certain drugs. It serves as one of the alleged murder weapons in A Killer Party.

Use in the Show
In the song, "Never Miss My Mark", Vivika reveals that she attempted to murder Varthur using an overdose of the medication with a dart laced with the drug. In the blackout, she took the poisoned dart from her purse and threw it at him, hitting him, thus nearly earning her the title of the killer.

However, it's revealed in the same number that George also attempted to murder Varthur, using a different drug called sugammadex with the opposite effect. It's believed that they are both the culprit, but it's later discovered that Vivika's attempt actually saved Varthur's life; while the sugammadex overdose would have killed Varthur with a heart attack, the counter effect of the atropine (slowing down Varthur's heart rate) served as a quickly administered cure.

Goofs

 * Vivika states that atropine slows and stops your heart when, in fact, its purpose is the opposite. It has multiple uses, but its primary use is to actually counteract low heart rate (bradycardia). A similar error can be found when George talks about using sugammadex; therefore, the effect in a fictional scenario would be the same, just with swapped names.
