First of all, props goes to the x-files special effects department for creating a quadruple amputee in Rappo, the disgruntled vet. I saw how they made Gary Sinise legless in Forrest Gump, but it still amazes me to see the x-files do it with a smaller budget. That character is totally believable as a quadruple amputee. While I am talking about special effects, I will mention that the effect of the phantom soldier is done very well too. When he is running through the stream and attacking the captain in the swimming pool, they're both quite convincing. Ian Tracey gives a great performance as the quadruple amputee Rappo. You can just feel his bitterness consuming him. It's hard to believe he really has all his limbs intact. Astral projection is an interesting term we learn in this episode to describe what is happening with Rappo. The Walk is a good, solid episode to enjoy.
