On Day 27, October 18, 2004, Locke (Terry O'Quinn) finds Claire (Emilie de Ravin),[3] but after she wakes up, she has no recollection of the crash, nor the other castaways, including Charlie himself. The next day, Ethan (William Mapother) confronts Charlie, and threatens to kill one survivor each day until Claire is brought back to him. Taking the threat seriously, several of the castaways set up security measures and traps around the settlement to avoid Ethan carrying out his threat.
