(Author's POV)
The night owls' whistles and hoots were echoing inside the dark forest as the sky turned pitch black, the clock indicating it was two thirty in the morning.
Greg was dozing off. Sara went to wash her face and the only one staying guard was Noah. Though, he too was feeling sleepy, but for him, it was still manageable.
A distinct noise interrupted his focus as he turned his head to find the source of this odd sound. It was dead silence for a few seconds and he returned his eyes back to the ICU ward where Bella was sleeping soundly. The clattering noise disturbed him again. He creased his eyebrows and wrinkled his nose in frustration, "Arth, what's that noise? Can you sense anything suspicious?"
"I don't know. I can't sense anything weird," Arth conveyed to Noah.
The thumping sound was heard again and Noah got up at once. He nudged Greg's shoulders to wake him up. Greg was completely of the zone and snoring loudly, his large figure was resting on the small bench.
