Gym open day

I convinced my brother to come to our gym open day and do the partner workout with me (the run, pull up, press up, wall ball, repeat followed by skipping box jumps and burpees one). I felt bad for shouting at him and forcing reps out him when he went very pale, disappeared and spewed. My "YOU'RE FINE, MOVE IT" was perhaps not the most sensitive of responses to his "I'm not OK"s. I wonder if he'll be back. We had a fun day, after that workout he left for the football but I stayed on for games and chats and another workout later on (where I nearly spewed too) and an aerial assault course. I later discovered there were videos of me shouting at him...oops...evidence! I'm sure revenge will follow.
