None of them

After reaching back home, Isabella ran towards Xavier's room. She can sense his presence there. The sad feeling didn't go away yet and something inside was telling her that it was related to him. The door wasn't locked so she walked in and saw him laying down on his bed, his eyes were open and staring at the ceiling. 

"What happened Xavier?" She sat beside him forgetting about the anger from before. The feeling was getting stronger with everything passing second. She could feel his emotions and pain. 

What could make him depressed like this? She wondered to herself. 

For a few moments he didn't move nor did he reply. She sat there looking at his blank face which showed nothing. A few drops of tears formed in his eyes and slipped on his temple. At that point, she had it enough. 

"Xavier please..tell me what is wrong?" Her hand went to his face as she wiped off the hot tears.
