You are a supernatural creature and in a sudden outburst, you unintentionally hurt Pyro and even though the RED team trusted you with their lives they couldn't just un-see that.

You were feeling guilty over everything that happened, you didn't want them to hate you or something worse.

You took a step towards them but was stopped by Spy's voice saying "Back off!" He said sternly.

Even Soldier cut you short as you tried explaining what happened. "Shut up!" Soldier said glaring at you.
