Philip Boyd

Archer, Reed and Hoshi are exposed to a highly contagious virus that transforms their bodies, minds and memories into those of long-extinct aliens from a tropical world.

A lonely telepath begs Hoshi to visit his faraway planet in exchange for information on the Xindi, then refuses to allow the linguist to leave.

Kelly accepts Brandon's marriage proposal; David buys a gun to protect himself; Noah's old friend Gwyneth reappears in his life.
