Jarrfan, Thank You for your insights. If we are Sasha, how would we feel walking up to a group of perfect strangers and asking them if we could join the group. First, we could detect some uneasiness within the group, after all, they very well could say no. Igor had already made up his mind to take us and it was up to us to convince the others that we would be an asset and not dead weight. This was simple for us, all's we had to do is be ourselves. Now that Sasha is in the group, he shows himself very useful and not dead weight. The hollowed out tooth is interesting and the first thing the should of done to see if it was big enough and dry enough for something to be inserted without saliva destroying it. Lastly, was the tooth stable enough so if he had some secrets in there and accidently swallowed it he would have to go fishing it out with a stick or something later. " Hey Sasha!" why are you digging around in the toilet?..lol
The tattoo's are probably just that and nothing more. He was in the war and they somehow are related to those experiences....Best Tim.
