Madam Caroline's end

"Too late?" Rex frowned. Soon his eyes shook, "What did you do?!"

"Too bad you can't find out, farewell, my unfilial son."

"Bang!" 

Just a second before she pulled the trigger, Piper barged into the room, causing the door to hit Madam Caroline in the back which prompted her to shoot the gun but missed her target.

Madam Caroline looked behind her to see who it was. She wasn't surprised to know

 It was Piper with tears in her eyes.

"You are here too, you both can die together!" Just as she was about to shoot Piper, Rex, who was already feeling dizzy, lurched at her and they started fighting for the gun.

Piper didn't know what to do. She still couldn't digest what she just heard. When she saw that Rex was going weaker and weaker, she searched for an object, anything that could be of help.
