As best I can tell Greg revealed his Parkinson’s diagnosis on March 4th 2025 via Instagram.
Additionally in an interview published June 25th 2025 on Twitter Greg said,
I received the call from WB right after being diagnosed with Parkinson’s. It’s been a challenging illness to deal with so It meant a lot to me that Sam Register the big boss president of WB animation/Cartoon Network called to say he loved me and thanked me for creating Beast Boy
This says diagnosed not publicly revealed. So it’s possible WB fired him on Valentine’s Day after he told WB, but the interview quote makes it sound like they are on good terms. It’s also possible Greg’s interpretation of events differ from WBs interpretation, as in they had a good chat, but he was actually fired.
There is definitely a lot of missing information. Also something clearly changed or was clarified in the past few days, because why did this happen now and not at any point in the last 6 months.
