Archer and Degra are on a ship together

Archer tells him about how they are jail buddies and he’s forgotten everything because of Xindi-bug interrogation

Archer tells him about how after earth was destroyed, the Xindi-bugs wanted to become the leaders of the Xindi

This whole thing is actually just Archer messing with Degra.

Through a flashback they explain how the captured Degra’s ship. All the data on the ship was erased except for some personal information about Degra.

Degra ends up giving them some coordinates

But then Degra gets suspicious

He says he figured out Archer a while ago, and gave him the wrong coordinates

So they put on another show for him. They act like they arrived at the coordinates. When he get’s really mad, they know the coordinates are for real
