It likes messing with peoples heads, make them think it's someone it's not, lure them into a false sense of security.
It enjoys the way they falter when they realize they've walked right into a trap, the look of dread when they realize they're done for, the pointless pleading for their life.
It lets the reality set in for them, that they were doomed from the start, because once this thing has it's eyes on set on a target it is relentless.
It plays the long game, taunting it's victim for somewhere in between days or weeks before finally making a move. It makes them look crazy, seeing things that aren't there and asking what someone said when they said nothing at all.
It's plan is all about isolating them, making them lose their mind before they lose their life.
It doesn't even do this for food, it's all for fun.
