In a situation like this.

My friend invited me to level in CP. It was all going fine until a high level mage offered the tanker 8s worth of SP pots so he can continue taunting the monsters. He did a stupid thing by dropping it on the ground, thinking that the tanker can pick it up. Our party was set to sequential item sharing, and the pots happen to appear in my friend's inventory. The mage then got pissed, not listening to anything we told him and then trained us all.

What to do in this situation? If i try talking to anyone - especially the mage, I would then become the suspect. If I just stood there and said nothing, I too would become the suspect.

What are you supose to do in this situation? What would you do?
