But don't get too bent out of shape — Alex's proposal was never part of the actual storyline. You see, this swoon-worthy scene came from Season 10, Episode 17 — "Do You Know?" — aka the episode in which Cristina imagines two possible futures.
Just when the assembled party wonders where Jo is, they spot her standing by the bus, looking shocked at the sight of Alex on bended knee. She happily accepts, they kiss, and Cristina shouts, "About time, Alex!"
Alas, Jolex supporters, 'twas not to be. Maybe Season 11 will be better to us!
Grey's Anatomy Season 11 premieres Thursday, September 25, at 8 p.m. ET on ABC.
