Marvel’s Agents of SHIELD has me worried. Concerned, even.

I’m afraid that something horrible is going to happen to FitzSimmons. I’m sure some of you are feeling it as well, and it’s something that’s hit us way too many times in Agents of SHIELD’s run.

Things are going well for Fitz and Simmons, the best that they ever have. Our two favorite scientists are finally on the same page with their feelings, whatever the cosmos want aside, and have taken that final plunge in the ending moments of this week’s episode. Their banter is as ridiculous as ever. Fitz is past his weird brain damage and Simmons is over her last love, Will. They haven’t lost a step.

All of this is why I’m concerned.

These are two of the most tortured souls (romantically speaking). When Fitz exclaimed episodes back that the bloody cosmos are against them being together, he honestly isn’t that far off. Let’s recap:

They have known each other for ten years. They’ve been on different pages with what they are to each other for so long, it’s almost been unbearable. It took them getting stuck at the bottom of the ocean by Grant Ward to get Fitz to admit his feelings and for Simmons not to be able to respond in kind, unwilling to ruin their solid friendship with anything more. She fled to freaking Hydra to get away/make Fitz’s recovery better.

That backfired for Fitz, who dreamed up his own Simmons to talk to, and when Simmons returned, things were even worse between them. By the end of the season, they have reconciled and come to a new understanding. Fitz made his move in the season finale, getting a “yes” to his dinner question, and trotted off to set up their date, only for the Monolith to suck Simmons to the other side of the galaxy (universe?).

The cosmos are against them. Because once Fitz did the unpossible and rescued Simmons from the mystery planet, he discovered that while she used her phone with his picture as her rock to keep her sane, she also fell in love with the only other person on the planet who she desperately wants to save. Because if he saved her, can’t they do the same for him? Or at least try?

He does his best. And even when he does the impossible again (this time with Hydra’s aid), he can’t save Will, and Simmons is heartbroken. They literally start their relationship over from the beginning this season, with a handshake and a “Leo Fitz”/”Jemma Simmons” exchange (over on the right there). This week, they discuss taking the plunge now that they are a “thing,” and it should come as no surprise that they both are fed up with waiting.

They’ve wasted enough time.

This couple has been through enough already. They don’t need to be put through any more. And yet… there’s this sinking feeling in my stomach that because this is a show related to the Whedon universe where nothing is sacred and anyone can die, we’re in for something horrible. Who’s going to die? It’s what I find myself thinking as we reach the season finale when one of our SHIELD compatriots will bite the bullet.

But FitzSimmons has already been through enough, in my opinion, and it’s time to stop beating a dead horse. The more you dip into the torturing FitzSimmons well, the more tired we will become of it. Agents of SHIELD already does a balancing act with so many main characters, the small moments we get with our nerdy scientists are a breath of fresh air from the stale seriousness that SHIELD tends to have.

And if you’re going to do anything with them, I vote to just do it to both of them. They’re going to be a package deal, even more than they already were, the new Bobbi and Hunter but with less hilarious banter and more science talk. If this show is going to kill off one of them, they may as well kill off the other. Or send them both packing to meet up with Bobbi and Hunter on their new show.

Just please, Agents of SHIELD, let FitzSimmons be. Don’t let their relationship get unnecessarily complicated now that they’ve taken the next step. And don’t torture them any more than the cosmos already have.
