Two Eyes Cenote one minute of everything at once

After fishing @Frolic out of her latest adventure (she seemed to crash into them rather the other way round), Dwin made sure that she was nice and dry and insisted on finding a den for them to rest for the night. There were some protests and arguments that she would have definitely lost at home, but out here she still had her ace card. They had a deal and Dwin had fulfilled her side of the bargain. 

Eventually they both fell asleep, each dreaming of different things. Dwin's sleep was restless - she kept waking up to check, if her younger sibling was still there. After all it was not all just the sense of responsibility coming from an older sibling. She also had given her parents promise to bring the little rascal back home safe and sound (despite her claiming of never ever returning home). Finally, she could no longer enter the dreamland. She carefully entangled herself from her still slumbering partner in crime and left the den to check out, what was going on outside. 

And good timing it was - she heard footsteps in the distance coming closer and closer, until a dark figure appeared and stopped to satiate its thirst. Dwin's body was frozen, while her gaze was fixated on the stranger, following his every move.
