From the episode script

• In the classroom, there are more educational lessons.

• After Adama makes the decision to let the ship go and Apollo and Starbuck leave his quarters, Tigh says,

Tigh: "The council will boil you both alive."

Adama: "My son may never come back. That ship could be on a phantom course set by some space pioneers a thousand yahren ago. You think I'm worried about what happens to me?"

Tigh: "Then why let them go?"

Adama: "Because the civilization we seek is getting close and I do not intend to destroy their first emissaries."

Tigh: "You instead risk your own son."

Adama: "What better sign can I give the council that I believe with all my heart that we are doing the right thing." :Adama turns to the window and Tigh places a hand on his shoulder.
