FitzSimmons have been the beating heart of S.H.I.E.L.D. since the series premiere, and were often the emotional tether that kept it grounded. “F.Z.Z.T.” remains a series highpoint and it’s because it was the first time the stakes felt real, but it was also the first time the relationship between Fitz and Simmons took center stage. So if you didn’t cry or at least tear up during their scenes this week, you might want to go to the ER and have your heart checked because there is a very good chance you are dead inside. Iain De Caestecker turned in what was probably his finest performance of the season as the episode gave Fitz a chance to play the hero and tell Simmons the truth about how deep his feelings for her truly are.
For her part, Elizabeth Henstridge’s performance was equally moving, first as the realization of what Fitz was telling her played across her face, and again when she refused to accept the plan as it was. “I never had the courage to tell you, so, please, let me show you,” Fitz begged, and it was the saddest thing the series has ever done.
