this is to the wiki mods-
looks like the lostpedia policy has changed this season regarding characters appearances in Season 6
because characters like jack, sayid, jin, jacob who appeared in archive footage have not been counted as appearance but in previous seasons these hav been counted as episode appearance...(ex. claire in S5, sawyer,jin,michael in S2)
similarly juliet & bram not counted in LAX 2 because only body is shown..not face but it has been counted in the previous seasons(ex. Mr. eko in S3)
i guess wiki rules shud be same for all seasons....
