Where is she?

One day during the late evening you get a call from your Packs Alpha Foster, he is looking for your best friend Alisha. She has left him, leaving only a note saying goodbye and that she will never come back. His younger brother Sila's is also missing. He asks you to come over, and you do because he sounds very drunk and heart broken. You go to his house and he is drinking. He is angry and waiting for answers about where you think Alisha went. He is broken, angry and looking for answers. But Alisha kept all of this secret even from you. You both talk and drink, him getting drunker and you getting drunk feeling sorry for him. How could Alisha do this to him. He has always treated her with love and devotion. Then as you two keep talking he suddenly kisses you. To your shock. The rest of the night becomes a hazy blur. You wake up in the morning in a strange bed, some one's arm draped over you and you realize in horror as you look into Fosters handsome sleeping face that you spent the night together.
