In the end credits of the first episodes, you see a close-up of Ed who "turns to the camera" and casts a faint smile. In the 7th episode though - a tragic one, Ed's smile breaks into a big grin while his eyes are shining like he's about to cry.
In the dubbed version, Episode 25: "Words of Farewell" has a different ending than the usual song, "Move Across the Door" (Second Ending Theme) by YeLLOW Generation, and ending sequence with no previews, instead, the ending song is a militaristic drum beat and the credits are shown against a black background.
The end credits usually start before the episode is completely over.
