So I got three votes I should have the Titans tell Robin and one vote they shouldn't. I'm not giving anything away so read to find out what happens.
The Titans continued to exchange nervous glances at each other not sure what to do. After a moment Robin got out of his bed, stood up and folded his arms giving glares at his teammates.
"I want to know what is going on", Robin repeated.
Starfire put on a fake smile and said, "Nothing is wrong Robin. I was just worried because you did not wake up yet. I thought that might of had the sickness".
"You're not a very good liar Starfire. I only slept in because I was up late working last night and because I have a headache. That is no reason to freak out like that", said Robin.
"We're not hiding anything from you dude, we just..." but before Beast Boy could finish Robin held up a hand to stop him from continuing.
"None of you are leaving this room until I know what you're hiding from me", said Robin.
After he said this Raven did a big sigh and sad, "All right we'll tell you".
Starfire, Cyborg, and Beast Boy turned to Raven with surprised looks on their faces.
"We can't keep it from him anymore, he needs to know", Raven told them.
Raven then took a deep breath and said, "We lied to you about not getting the x-ray results yet. We did get them".
"Okay, why did you lie about that", Robin said while getting worried about what she was going to say.
"We got the results on Monday. They said...you only had a week left to live", Raven said kind of quick as if to get it over with.
After Raven said that Starfire burst into tears again and hugged Robin tightly. Robin didn't return the hug because he was too much in shock.
"What?" he said after a moment.
"You heard me, you have brain cancer and that's why we freaked out this morning. You could die any time now", Raven said sadly.
Beast Boy and Cyborg also had sad looks on their faces and Starfire was still crying and hugging Robin.
Hoped you liked it. I'm sorry for the short chapters but I keep getting to parts where I want to end the chapter and sometimes that makes it a short chapter.
