The following post contains SPOILERS for the new issue of Steve Rogers: Captain America #1, which is on sale now.

If you’ve been cruising social media today and you follow any comics fans, you probably caught a glimpse (or several thousand glimpses) of a #SayNotoHydraCap hashtag. That’s because the brand-new Steve Rogers: Captain America #1, written by Nick Spencer and illustrated by Jesus Saiz, ends on a whopper of a cliffhanger about the Sentinel of Liberty:

Yes, Steve Rogers, America’s greatest hero for more than half a century, the idol of millions, is (or at least appears to be) working for Hydra. Spencer told Entertainment Weekly “This is not a clone, not an imposter, not mind control, not someone else acting through Steve. This really is Steve Rogers, Captain America himself.” And that has some readers quite upset. (I’m not going to reprint their tweets here, but again, just go look at the #SayNotoHydraCap hashtag.)

While Rogers has been going strong in the Marvel Cinematic Universe for the last five years, he’s been out of action in the pages of Marvel Comics. A few years ago, the Super Soldier Serum in his blood that kept him young stopped working (because comics) and he rapidly aged into his 90s. He kept working with the Avengers to plan missions and such, but he was effectively out of commission as a superhero. (Sam Wilson, aka Falcon, replaced him as Captain America.) Steve Rogers: Captain America #1 was supposed to be Rogers’ big return to action — and then it dropped this crazy swerve in people’s laps.

As a longtime comic book reader, here is my advice to anyone who is genuinely upset about this reveal: Take a deep, cleansing breath. This is the first part of a longer story. In recent years Steve Rogers has died, come back to life, gotten really old, and then gotten young again. Back when I was a kid he was slowly dying and had to wear a goofy suit of armor for a while. A few years before that, he turned into a freaking werewolf!

You know what happened next? He got better! Cap always gets better. Nothing ever really changes in these books because there’s always a new issue next month. Crazy twists like this should be the thing that makes reading ongoing comics fun. So sit back, relax, and enjoy the ride.
