User blog comment:PUNCHURPREGNANT/Gray and Silver Predictions/@comment-24070575-20140228021946

Well... I have a pretty good one, in my opinion. ---theory--- Gray is Silver's younger self. ---evidence--- 1. (This one is pretty useless but well) Gray and silver are very alike colors. 2. Gray is the only one able to control Silver's ice. 3. Silver know both Gray AND Natsu. If silver has been Grays dad he wouldn't know Natsu. I forgot what chapter was it but silver asked himself this question, "Natsu... Why of all people". Admitting he knows natsu! 4. Their features are alike. Black hair and blue eyes. ---possible outcome--- I am guessing, not sure. -theory- Silver has no evil intentions in the Tartarus Guild. He is actually undercover.(Has happened before in one of his mangas) He might be researching something. trying to become friends with the enemy and then looking into their plans. Gray meets with him and Silver would explain him what is going one, but it wouldn't make sense since Silver doesn't want to be associated with Gray.

Well but he might as well be his dad...
