Character auto deleted

You are probably right about her not choosing free option before TBC and being auto moved to TBC later on. However if that is the case she should first look at Mograine PvP EU due to Dreadmist PvP EU realm being consolidated and as all characters from all consolidated TBC/Wrath realms who didn’t took provided free character transfers, her’s were moved to Mograine PvP EU Wrath Classic as well.
