My personal thoughts are that since both people who have been attacked multiple times are from the Order of the Hand, the attacker is one of the other lower members of the Hand looking to be promoted, another Order is looking to take control of the voting by eliminating us, or the mafia is trying to kill the healers first so the rest of the kills will be easier.
If it is the first option it may be too early to tell who the attacker is since it would be a vigilante and not scum. If it is the second option the Order of the Staff is looking healthy in comparison to the other groups, but once again it is vigilante attacks and so would be difficult to point fingers.
I believe the last option is the most likely. The first night Gone 3 the Celt had good reason to be vigilanted, leaving me an open target. If I had not been a defensive stance more damage might have been done. The second night john was attacked twice, possibly because the attack on me the night before was met with resistance, so they moved to an easier target. He has been attacked every night since and has only survived due to healings. Last night both of us were attacked.
The inconsistency of attacks per night is very interesting. Night 3 obviously had much vigilante activity. We know there have been at least 3 attacks per night, possibly meaning all three scum can attack at night.
However, I am a humble apprentice and know that my superiors probably have more insight than I.
