The premise of this piece is brave and ambitious: the protagonist is trapped in a building, pinned down by enemy fire, with another soldier not on his own side. It's up to him to overcome the soldier's suspicion and develop some kind of fragile rapport.
This is a intriguing idea, and it starts out well, with several neat exchanges and revelations. But ultimately the conversation is not entirely satisfying: the protagonist is under-characterized, the enemy soldier a little too unsubtle in certain respects. Some pieces of the dialogue could have stood to vary more with repetition or context, too: not all of the lines are equally appropriate in all the contexts in which they can arise.
Still, an interesting piece of work, especially for those with a taste for character-focused IF.
