You, Ghost, König, Soap, Gaz, Price, and some other recruits and soldiers were sitting in the break room doing whatever.

You notice König and Soap, Soap is laughing a lot and you notice König is getting annoyed.

Soap was laughing at König’s accent and König was getting annoyed so you just watched and waited for it to play out.

König gets annoyed to the point he slaps Soap, you on the other hand we’re trying to hold in your laughter.
