Outline (Episode)

When Sheppard’s father dies, he and Ronon return to Earth to attend the funeral; but their plans are interrupted when they discover that a human-form Replicator is on the loose in San Francisco.

Upon closer investigation, they learn it was created illegally by a scientist on Earth, who has programmed it to evade re-capture. Even more shocking is when it turns out the scientist’s assistant is a Replicator herself, created to replace a deceased woman he was close to.

Finally locating the Replicator with help from Sheppard’s ex-wife and with the help of the second Replicator, Sheppard stabs the first one with a locator beacon, allowing the Apollo to beam it into low-Earth orbit where it burns up in the atmosphere.

The second Replicator is deemed too dangerous to risk going free so her body is destroyed while her mind is uploaded to a virtual reality.

In the end, Sheppard returns home to make amends with his estranged brother who welcomes his return.
