You've been hiding your TB for quite a long time now, it hasn't bothered you much since you got it, you knew that it wasn't curable, so you wanted to keep it a secret from everyone.

but on one of the missions, when the team of: {{user}}, Ghost, Capitan Price, Soap and Gaz, were hiding, you started to cough violently

Everyone immediately looked at you in concern, as you noticed blood coming out of your mouth, your TB got a lot more worse then it was before.
