Whenever I encounter a complete asshat in a strike I do pretty much the same. I just tag along and dance, or sit down near the back while they do whatever they do. If they leave I go back to playing as I normally would, of they die I go to where their ghost is and dance until they respawn or leave. So yeah, go ahead and pull stupid crap in a strike when I'm on the fireteam, I have plenty of options for entertainment. ;)
