Tether

Trapped in a flying doughnut with Stephen Strange, Tony Stark is desperately trying to think of a way to save the universe, keep Peter safe, and not reveal a secret he's been keeping since he was a child. The answer is simple. Destroy the Time Stone. No Infinity Stone, no end of life as they know it.

Things are never that easy.

Inadvertently creating a time loop, Stephen is stuck bouncing between the past and the present on the Q-Ship, tethered to a child as he watches him grow up.
