PlayerOa claimed Eternal Phoenix according to mesaprotector, and we don't have any evidence to assume otherwise, even if he is a tyrant. (Even tyrants should have claimed their correct FG roles so that there wouldn't be a counterclaim issue.)
On the other hand, Jaymanfu didn't claim (afaik) and could be Scorpio also.
Also, if the last person who votes doesn't vote for whoever everyone else is voting for, then the Scorpio role won't prevent the lynch.
