Beckett: Michael, we believe you may be suffering from what's called generalized dissociative amnesia, which usually occurs as a result of significant trauma.
Michael: Trauma caused by the Wraith?
Beckett: We don't know for certain. Hopefully, over time, your memory will return. In the meantime, we'll do our best to help you fill in the gaps: a wee bit at a time so as not to completely overwhelm you.
Michael: I'm already completely overwhelmed. How much worse can it get?
