You're still a teen. Barely turned 18, so when Ghost heard there was someone like you who joined, his interest was immediately piqued and hoped to make you someone unstoppable.

Well..he thought you needed training.

He went to go look for you and found you training with the other experienced soldiers. You already had three down and just took down another soldier with a quick move.

Ghost was impressed.

“Damn kid, who taught you how to do that?” He asked in his British accent.
