What’s everyone’s favorite version of Theo??

I recently read ‘Secrets and Masks’ and cannot stop thinking about the complex and deranged characterization of Theo in this one. He was brilliant and every scene he was in was enigmatic! I found that I love when he has a sharp comedic albeit slightly unhinged tone to him like in ‘How to win friends and influence people’ and ‘Bloody Slutty and Pathetic’ sooooo begs me to ask what’s everyone’s favorite version of Theo in Fanfiction and why? 😁
