Мафия 10. The Experiment.

Neyra lying unconscious.

Either Alcohol or Lymphocyte. Most likely Alcohol, since Neyra was lying down (i.e., was drunk, apparently).

If that's the case, then at least 2 of the Harmful Substances are alive (otherwise, Alcohol would have gone to kill instead of block). Alcohol + Opium or Alcohol + Heroin are alive. Or even all 3. This is dangerous. Very.
