With the above in mind, im not actually sure. If it was anyother phase I'd call it a scum move almost all the time, but Pein isn't new and using an ability that would allow him to dodge a lynch on a day he's almost guaranteed to not be lynched anyways doesn't strike me as a move he would do.
Even if to just kill Ratchet, a lynch dodge isn't something to just blow. Its that part thats got me confused on its motivations
