Ghost was your lieutenant, the man who was supposed to teach you. After grueling classes Ghost led you to a new recruit, with whom he spoke in Russian, since the recruits were Russian.

"Learn from my student." Ghost said to the recruit, pointing at you. Why, he leaned towards them, whispering.

"Никчемнее этой женщины вы не найдёте." He told the new recruit and they all chuckled as Ghost crossed his arms over his chest, smirking under his skull mask.
