Credit where it's due. He was a slippery rat indeed. He was very difficult not just to catch, but to hold him down aswell. He did cause a headache, but was fun.
The player knows how to build a good infiltrator, and I hope he comes back to build another.
Building a good infil takes ages. Even if he does come back, I doubt Spearhold would ever see him as an infil. First you need the honor and prestige and then the swordfighting and the infil at insane high levels to be effective.
