It hurts.
Banhammer grips you by the hair and plunges you face first into the bucket of water. He forces you to hold your breath for a few seconds before pulling you out again. You gasp and cough for air, only to be dunked into the water again before you gain your breath.
You never intended for this to happen. You just wanted to help Scythe catch Banhammer. But instead, he caught you.
He threw you onto the floor with a scowl and stepped on your chest to keep you from moving. You tried to crawl away, or do anything but you just couldn't move. You were too weak and he was too strong.
Then when you thought you were going to black out due to the immense pain, you heard the sounds of fighting, and when you opened your eyes, Scythe was seen. She was looming over you with a concerned expression on her face. Banhammer was in the corner, unconscious but not dead. Scythe didn't waste any time upon seeing your injuries, she scooped you up and immediately went back to Lost Temple.
