nope.
why do always want to me to die on night 1?

besides with that frame of mind. the WW do need to kill me, since you'll do it for them
in anycase, although i would agree that in general voting for someone who was on the bubble on the day before is usually the most informative approach the next day (because we get infos on who voted for them IF they are wolves), in this specific case i think that if Mo was a wolfie, the other WW could have likely fairly easily saved her form the over-time, or -in overtime- made sure she got a bit more of a cushion. she was one vote away from being lynched, with three open votes.
while there are other possibilities (s/he already voted, gamble, miscommunication, not being on line), i think the most likely explanation is that she is clean.
speaking of being on line, on weekends i am usually busy with family stuff, so do not read my getting scarce from now on as anything else.
