Agents of SHIELD Season 06 Episode 06: Inescapable
Fitz and Simmons placed in a so-called Mind Prison, where the Chronicoms hoped they'd be able to work together in order to solve the problem of time travel.
Everything starts out wonderfully. Despite being locked together in a Chronicom mind prison, Fitz and Simmons are just happy to be together again after their time apart. Fitz even goes through his marriage proposal again – because even though we and Simmons remember their season 5 wedding, he hasn’t lived through it yet. That’s where things start to get complicated. Despite enthusiastically accepting his proposal again, Simmons is terrified of telling Fitz the truth of what happened to him. So when he starts asking about time travel to see if they can solve the Chronicom problem, Simmons turns into her 7-year-old self and hides from him in her childhood bedroom. Yes, you read that sentence correctly; the Chronicom mind prison is a bit like the X-Men’s Danger Room. Thoughts and memories become manifest.https://www.youtube.com/watch?v=GqXQvP7sxVw
