Мафия 65. S1-ut system: criminal scum strikes back!

I didn't understand this at all – can you elaborate on why the second mafia doesn't have Night Defense (ND)?

Scavenger - II. Field of Death: places explosives on an area where the target is located and kills the first person who approaches it, as well as the target and other guests with a 25% chance. Once every two nights.
Nigel - ult. EMP Pulse Bomb: The ND of the city and the first mafia only has a 50% chance of success.
They are both from the second team of mafia players.

So, I understood that Alexigl could kill Wolfset, being the original mafia player, right?
