Somehow I think that this event was the making of more than one man. Both Berat's and the boy's lives will certainly be forever affected by that horrible moment.
For some reason, reading this, I was seeing it cinema-style in my head -- no music, just the juxtaposition of the laughing and joking Cardassians trying to reach out a bit with the kid and his heavy breathing and his heartbeat pounding as he raises the gun ... making everything seem super-ominous. A well-crafted entry that shines a light on an important moment in Berat's past as well as makes me wonder who exactly this child will grow up to be.
Good work, as always!
