Might As Well Jump!
The island holds an energy source that allows for the possibility of time travel. Cool! Unfortunately, a lot of our Losties are randomly jumping through time. If this doesn't stop soon, they'll be in trouble. Daniel Faraday manages to get a message to Desmond, who is off the island with Penny. By talking to him in the past, he's creating a memory for Des in the future. We know. It messes with your head. Anyway, Desmond must find Faraday's mother at Oxford, as she can help.
