Mafia 20. Radioactive Dreams.

If guests came to visit, they were supposed to take turns. But here, two came at the same time...

Don't make things up. This is a description of a single action. Either hysteria or hiding in the dark.
Tonight, the smokers could only have had two Night Deeds (assuming two players were killing). That is, either there was a "kumar" on one player, or hysteria.
Hysteria and kumar happen before all the killings, so in any case, they were used, or the players were blocked.
