Charlie has flashbacks to five of the greatest moments in his life. They are: 5) when he heard his song on the radio, 4) when his dad taught him to swim, 3) when Liam gave him the family ring, 2) when a woman called him a hero, and 1) meeting Claire.
Karl comes to warn everyone that the Others are coming sooner than they expected. Danielle is helping them to stop them by blowing them up with dynamite. Sayid learns of the Looking Glass station underwater, where they'll be able to communicate with the outside world. Desmond has another vision of Charlie's death. Charlie volunteers to swim there and pull the switch and potentially drown. Jack leads everyone else to the radio tower where they might communicate with Naomi's phone. Charlie arrives there, but there are two people standing guard that catch him.
This episode was great! I really enjoyed the flashbacks! I loved the ending! It was a sad episode...I give it a 10 out of 10!
