Brash foursome! Coach vs. Stepfather!

Morielle and I were training and had to go to the bathroom for a moment. Since it's a communal bathroom, our trainer suddenly stood there too. We had a normal conversation and the next moment my stepfather suddenly appears in front of us and makes a totally exaggerated scene for us! You can't imagine what happened there. When Morielle came out of the bathroom stall, he started accusing her too. Oh God, what happened next was actually my fault. Should I have whispered that in her ear?
