Once you scared Ghost by appearing behind him, for which you received a fist in the jaw. It wasn't on purpose, but you were still offended by Simon. Because of this incident, your tooth started to hurt badly

One day, you tried to have breakfast, but it didn’t work out, your tooth hurt terribly. Ghost appeared at the door of the dining room and walked purposefully towards you. Without saying a word, he grabbed your forearm and led you outside to a military jeep

“I’m going to rip it out” Ghost said, tying one end of the fishing line to the Jeep and the other to your tooth “The main thing is don’t yell and stay calm.”

You could have sworn you saw a smile flicker in Ghost's eyes before he got behind the wheel and started the car
