Gibson was dismissed from the series following an alleged physical altercation on set
“Lot of birdies chirping out there. The gossip is real. I hear it. I see it,” he tells the camera in the since-deleted clip. “I’m sure a lot of you do too, so I’ll just say this: I believe in karma. Good things happen to good people, honest people, hardworking people, humble people. People who believe in basic goodness, people who believe in themselves, people who believe in others.”
“Good things will happen to you. It’s not always easy, but you’ve got to grind it and you’ve got to believe in you,” continues Moore, 46. “Treat people how you expect them to treat you. Celebrate yourself, celebrate your blessings – as you should. But just know that you’re not better than anybody – we all have our own gifts, so unwrap them bad boys and show them off, but then appreciate other people’s gifts.”
Moore previously starred on the show alongside Gibson for 11 seasons before exiting the CBS drama earlier this year. Though he later deleted the video, it was captured by a fan and reposted on Twitter. And while he didn’t name any names, fans of the hit series speculate that he may be referring to Gibson’s dismissal last week over an an alleged physical altercation on set.
Following the incident – which a source told PEOPLE occurred about two weeks ago while Gibson was directing and starring in an upcoming episode – the actor was initially only suspended before being officially let go on Friday.
“Thomas Gibson has been dismissed from Criminal Minds,” reads a statement released to PEOPLE by ABC Studios and CBS Television Studios. “Creative details for how the character’s exit will be addressed in the show will be announced at a later date.”
In response to his dismissal, Gibson, 54, released the following statement to PEOPLE: “I love Criminal Minds and have put my heart and soul into it for the last 12 years. I had hoped to see it through to the end, but that won’t be possible now. I would just like to say thank you to the writers, producers, actors, our amazing crew, and most importantly, the best fans that a show could ever hope to have.”
Criminal Minds returns for season 12 on Sept. 28 on CBS.
