Scully: Wouldn't your client find it somewhat inconvenient to be thawed out in the future, only to discover he had no functional mobility?
Barrington: We believe that by the time science figures a way to revive our clients...
Mulder: ... you'll also know how to clone new bodies for them.
Barrington: Exactly. This technology is progressing faster than anyone thought possible. Ask anyone here at the university. So, while for us the passing of each second brings our bodies closer to death, for our clients it brings them closer to life.
