What is the veteran's name in rabbit Redux?
The veteran's name is Skeeter and he is claiming to be a Black Jesus when he comes to visit Harry and talk about the war and in particular race relations in the war. Skeeter comes into the story and really upsets things because they had been going passably well for Rabbit until he arrived.
Skeeter is mainly there to do drugs and try to convince Rabbit that he is right about all the problems in the Vietnam war and particularly the ones having to do with race relations. Skeeter is an example of the particularly tortured characters that Updike often comes up with as he is patently unwilling to have simple, scripted stories with predictable characters.
