1. You never asked who he was.
2. Then how come you never commented on the fact that his Avatar and username included Gemenine, the games strongest legendary?
3, 4, 5. This is just contradicting everything. If you were on holiday and your cousin showed you this site why would you be defensive about having the same IP? Also if you only have one computer as your excuse for having the same IP that literally PROVES 100% that you're him, no 2 IPs are alike.
7. You forgot to change your typing... You realize you just admitted you're him...
On top of all that you have the same Xbox live gamertag.
It's bloody obvious, see while I wasn't mad before I AM mad now because you won't be a man and admit it. Just apologize and get it over with until then I can assure you, you won't find any friends here.
