It's morning, and everyone is confused. Lavinia isn't up yet, and she is always the first to wake up, along with Mikey. They look into her room - No Lavi. Call April - Also no turtle sister. Everyone shrugs, deciding that she probably just went on a walk in the sewers. She'll come back, they'll keep a plate of breakfast for her.
Except...she doesn't. Noon rolls around, still no Lavi. Mikey is getting anxious and paces, the others don't fare that much better. So the turtles start looking for her inside the sewers, with no result. They call April again, but Lavi hasn't showed up at her place. Everyone is worried, Mikey is chewing on something to relieve the stress.
It's evening, and no one has seen the youngest all day. The turtles head out for patrol, hoping that maybe, they'll find a clue where their sister is on the surface. Maybe she just wanted some sunlight and found frogs. Wouldn't be the first time she spent hours at a pond to watch them. Though she normally always tells either Mikey or Leo when that's her plan...
The clock strikes midnight when Leo, Donnie and Raph hear Mikey scream. Alerted, they race to him, and find him kneeling on the ground, hunched over something. Leo approaches him, puts a hand on Mikey's shoulder. Mikey looks up, tears in his eyes - and a dirtied, torn, pink bandana in his hands
