Things weren't looking so good for Diem Brown at the conclusion of last week's episode of MTV's The Challenge. And, sadly, we all know they're not going to get better.

The beloved Challenge vet died on November 14, 2014, following her third bout of cancer. As we learned at the time, Diem was competing with her on-again, off-again love, Chris "C.T." Tamburello on Battle of the Exes 2, which is now airing, when she fell ill. Last week's installment concluded with Diem curled up in bed, moaning in pain.

Previews for Tuesday night's episode show C.T. panicked over his partner's state and calling for a doctor. In this exclusive clip, we can see that Diem has left the house for treatment and her castmates are eagerly anticipating her return. They're even crafting.

"We're going to take that shoebox and on this side, everybody's going to sign in, write a little something or whatever," art director C.T. explains as the camera zooms in on Sarah Rice drawing flowers and people passing stickers around.

"Hopefully, it can be like a welcome home present," Rice explains. A montage of Diem's toughest competitors scribbling with colorful markers follows.

"To one of the strongest, bravest, and most amazing women I've ever met," frequent villain Johnny "Bananas" Devenanzio writes on the box.

"So happy that you are home, beautiful! I know this only made you stronger babe," Nia Moore pens in purple.

"You know tomorrow when she gets back, she's going to be hugging everybody one at a time," C.T. predicts. "When she comes back and she sees this little care package we made for her, it's going to make her feel better and bring a smile to her face."

Whether or not Diem comes back to the house before she has to bow out of the competition remains to be seen, but one thing is for certain: C.T. was with her until the end. The Real World: Paris alum shared photos and support for his longtime love throughout her time in the hospital and even reportedly proposed to her just five days before she passed away.

"You have always been My Angel. And now you have your wings," he wrote on Instagram following her death. "We've been thru so much over the years. Thru the ups and downs we somehow managed to keep our promise. We never gave up on each other. … You are The Love of My Life. My reason to be a better man."

The Challenge: Battle of the Exes 2 airs Tuesdays at 11 p.m. on MTV.
