Here's what went down: In a teaser for the reunion shared by Sutton herself on her social media, at one point, we see Kathy Hilton join the main cast on the sofa. It then appears that Sutton falls back on the sofa, moaning, "Whoa."

The other women quickly ask if she's OK.

Garcelle Beauvais, Sutton's closest ally on the show, says, "Can we call somebody please?"

At that point, a paramedic appears, with castmate Annemarie Wiley, a nurse anesthetist, buzzing nearby as well.

We hear host Andy Cohen state, "You're shaking. You are really shaking."

The scene adds up to a truly dramatic moment, in which Sutton's castmates seem truly worried about their friend.

So what happened? We don't know for sure because Sutton hasn't directly addressed the situation yet. Her health emergency could have been a result of one or more of the reasons stated above. Or, as one fan joked on her Instagram, "Sutton are you allergic to Kathy?"

But the health scare was more than just a storyline it seems, as it was reported Sutton had to leave the reunion in an ambulance. It's rumored that Garcelle accompanied her to the hospital.

Sutton may simply have been suffering from dehydration or low blood sugar following a long day of filming. Either way, she was released, and recovered enough to go on a Mexico vacation recently with her son, per Page Six.

No matter the reason for her health problem, here's hoping Sutton is on the mend and getting better physically and emotionally following what was a very grueling and personal season.
