I was not very active and I culdn't use my power because I never was online after 22:00 GMT. That's why I couldn't save johho that night and I realized he was the seer the next morning when I read J. Pass' PM.
You should have send the GM a conditional order: "If Johho or me get lynched, lynch somebody else (with one or more names) instead".
Most GM's will honor that, but they may forget ;-)
Lots of people seem to be unaware that doing this is an option, though.
