The Time To Meet

As the big drops of tears rolled down his cheeks ,a voice came from behind.It was his sister,Allison . He ran towards her and hugged her as if it was his last time meeting her. But who knew what was about to happen..

Allison knew all that had happened .She knew that he was going to do it one day so it was not a big shock for her.She knew the truth why he did so but she couldn't speak, as if her lips were sealed. Meanwhile the sheriff pushed them apart and broke their wee-bee reunite. He dragged Tyler to their lighting omelion ( a place where the thundergods used to meet). Being used to all this Tyler once again showed no sign of interest. As soon as they reached their they both changed to their real forms.

Tyler remained silent.

Why did Tyler hugged Allison as if they were meeting for the last time?? How did Allison knew what all had happened??Why did she knew that it was going to happen??What was she hiding??
