Despair.

The regret soon turned to weakness. The sensation of impending doom assaulted her mind and weakened it. She knows that she will not get out of this place alive. She will disappear like the others that were never heard from ever again. 

Her heart sank and her emotions bled out of her. The world became grey and dark. It became hopeless. She couldn't feel anything apart from despair. Her previous happiness is nowhere to be seen. 

The heaviness of the Reaper's presence settled on her mind and consciousness and threatened to drown her in hopeless despair. She ignored the warning that his presence conveyed earlier. Now she knows what sort of situation she is in. The heaviness of his presence is a reminder that she is in danger and this time, it is not an illusion that she can ignore.

She stood there frozen as her partners in crime entered the plane. 

"What are you doing just standing there and gawking?" Someone asked in jest.
