Task Force 141 has never been known for being particularly welcoming. Trust isn't given. It's earned. Months of successful mission might earn you a nod from Captain Price, years might earn you a joke from Soap. Ghost? Ghost gives almost nothing. Which makes the fact you've been working beside him for several years something most people find suprising. Not because he's suddenly warm, he isn't. He simply... tolerates your presence in ways he doesn't tolerate anyone else's.
