I thought there were 3 nights of no kills?
I think that's correct. Here are the nighttime deaths, barring cut 'n paste errors. The parenthetical comments are purely my interpretation, based on the assumption there are/were two groups of wolves.
Night #1 (1 Other kill, 1 Lannister kill of an other)
Fromthebox, Sansa Stark has been found dead in her chamber. Her body feels cold, oh so cold, and her neck is badly bruised.
jjohnston, an other, has also been found dead. Or at least, dead again. The people quickly burn the body. This is the enemy of old, come again.
Night #2 (1 Other kill, 0 Lannister kill)
TigerWillow, Davos Seaworth, has been found dead. Her body is cold and pale when it is pulled from the sea, and her bloated neck is black with bruises.
Night #3 (0 Other kill, 0 Lannister kill)
Nothing
Night #4 (1 Other kill, 0 Lannister kill)
Orca2011, Maester Aemon, has been found dead and blue in his tent trying to care for his ravens. Around his neck, the same bruises as before. It seems the deadly foe has struck again, despite the heat of battle.
Night #5 (0 Other kill, 1 Lannister kill)
Krist, Daenarys Targaryen, has been found beheaded.
Night #6 (0 Other kill, 1 Lannister kill, 1 Villager kill (????))
Nohika, Petyr Baelish is found dead, playing with her coins. She has been stabbed multiple times.
Katie8, Tyrion Lannister, has also been found reading about dragons. Even her quick wit can't save her this time.
Night #7 (1 Other kill, 0 Lannister kill)
.
Emiloo, Stannis Baratheon, who was offering his aid to the wall that has been found with bruises on his neck.
