Aaaand here we go again!
Let's see: village of 22, five of which are infectors. One out of four. Every fourth person. Starting from the top, and excluding myself, that's
Lottie,
Zil,
Urwen (

),
Mac and
Sally. There, case closed.
Also, out of the next four people posting after me, one is bound to be an infector, right?
