Fitz’s biggest problem is Fitz. He’s trying to pull an Olivia Pope by grabbing the reigns of his presidency (#BullFitz), but his personal and emotional life are a complete mess. Like Olivia, his gut is fucked up and he’s just made a huge mistake in that hostage situation.
Fitz straight up hates himself and his life right now, but he’s still doing things out of duty (sex with Mellie). Everyone is like a Judas to him right now. I have every confidence that something will happen soon to force Fitz to man up, so to speak, and deal with his feelings. He’s a highly emotional man. Because of this, when he fails to satiate his emotional needs he cannot function. Well, at least without the brown juice.
Get your life, Fitz.
