The Bats have this running joke of convincing people that Tim is a cryptid taken in by the family. In a family of arguably strange people, the rest of them decided that it would be hilarious if they started rumours that Tim is some kind of creature. Jason and Steph whispering frantically amongst themselves that Tim got out again and scramble to leave a function that leaves other heroes like 'what the hell?' Damian is ordering a lot of raw meat over the phone (it's for Goliath, Titus and Ace and the hyena he's petsitting for Harley) and the Teen Titans ask how come because he is a vegetarian, is he feeding the meat to the bats in the Cave and Damian just looks a little disturbed and goes, 'No, it's for... Tim.' Cass excusing herself from a gathering at the Manor where Tim is absent, lugging bucket of fish to somewhere in the house. And not to mention the eerie voice notes that is mostly growling and snarling and garbled incantations that Dick quickly pauses when somebody wanders into earshot. And the strange leaked footage filmed by Duke of a vaguely contorted silhouette of Tim, hunched on a rooftop, the eyes of his domino mask just catching the light just so before he scrambles to attack the camera.
