Re: Battlestar Galactica 4x18: "Islanded in a Stream of Stars"
I think it's a legit two parter (or three parter depending on how you want to qualify the finale).
That's my understanding. The order for the final season was 22 episodes, counting Razor as two. That means two episodes were always planned to follow "Islanded in a Stream of Stars." I think "Daybreak Part II" just got expanded to two hours in the writing process, and they were able to convince the network to go along with it.
