Mikey is the happy-go-lucky one. Always laughing, smiling, pranking...heck, he'd be awarded the most smiles award if there were one. When Mikey screws-up yet again, his brothers decide it is the last straw, and decide to give Mikey a dressing-down. And a very angry one at that. Everything goes downhill when Mikey decides to take his brother's harsh words to heart. Will they be able to save Mikey from himself as he changes for the worst? They sure hope so. Leo, Donnie and Raph venture into Mikey's mind, trying to save their brother before he becomes their worst nightmare. How will they unravel Mikey's secrets? Will they be able to help him in time before it is too late? Or will Mikey they knew and loved be lost to his dark side forever?

When Raph and Leo are injured after a failed attempt to save them, Mikey is left with overwhelming guilt. But what if Mikey's episode of self-blame resulted in something much more severe? Will they notice when the youngest breaks down? ⚠️t/w - addiction, overdose, suicide mentions
