2D used to be a man that was all smiles. He found light in the darkest places. Despite how shitty his day was, he'd always put on a happy face.
10 years later, that happy-go-luck guy just isn't so happy go lucky.
Hearing his little sister was dead was the start of his sanity slippage.
Kong reminded him too much of her, so he moved to Paris and became a model. But he was bored with life. When he wasn't at a photo shoot he was staring blankly out his apartment window as people went about their business of doing what they wanted. Then Murdoc gassed him and brought him to his island.
Being locked in the bowels of Plastic Beach with a whale as a watch guard sent him over the edge.
For almost three years Stuart never smiled. He was either too busy cowering away from his bedroom window, the window the whale would peer into and spy on him…
Or he was loading bullets into a gun and firing shots at angry pirates.
Either way, a frown was etched onto his pale features. It was almost like someone took a permanent marker and drew one on his face.
Everyday he was waiting for Murdoc to forget to feed the whale and it would come for 2D to eat.
He hated Murdoc. He hated himself. He hated everything and everyone that was happy while he was miserable.
Even though it's hard to imagine, Murdoc wasn't as insane as he is now. He just put on an angry mask.
His grip on reality loosened when he sold his soul for Gorillaz.
Yes, he making a deal with Satan himself would cause his appearance to change, as well as make him go bonkers.
Living on Plastic Beach alone gave him a bad case of cabin fever.
This just sped up the insanity taking over his brain.
He knew that if he were to ask 2D to sing on his new album that's he'd do it, even if he had to threaten the blue haired singer. But he instead kidnapped and tortured him because insanity will make you do things like that.
Even with 2D at the island, locking him in the bottom of it still made the bassist alone. He began seeing and hearing things. He'd dart his eyes from left to right, following the orbs that used to dance freely in front of him.
He'd laugh at how pretty they were, but how stupidly they would dance. He even thought his brother died and was trying to contact him from beyond the grave.
Russel's craziness happened before anyone else's. Witnessing his best friends get shot edged him closer. Realizing they were inside his head gave him a sense of closure and brought him back to the mental state he was at before the tragedy.
The Grim Reaper taking them from him unscrewed a few bolts in his head. Ever since he's never been the same again…
Noodle suffered sanity slippage at an early age. Having been a child super soldier and almost dying when the project was terminated, it's a wonder how she managed to be happy.
Going to Hell made her sanity level lower than it was when she was 10.
When arriving to Plastic Beach, she found Murdoc sitting in his study mumbling little nothings and pointing and laughing the 'orbs', and 2D silently giggling at the thought of his demise by the whale.
