BELIEVE ME OR NOT, HE WAS HERE

After Chris and Adam are gone, Karen went inside her room trying to wander her mind about what happened between her family and Chris. She never expected him to eat her mom's food…..he keeps on surprising her. He was in a hurry to leave but when her Mom offered him some food, she was hoping he would decline but he didn't instead he ate her Mom's dishes. She thought he was an egoistic person who wouldn't try that but he kept shocking her after shock. Who exactly is he? Why does he keep duplicating his personality.
