cast of Doctor Odyssey, investigating a crime on their cruise ship. Her involvement will center around protecting the ship's vault for engers that want to break into it. It's not her character's first time on a cruise ship, either, having survived when one she was on sank during 9-1-1 season 7.

Speaking with ScreenRant, however, Stark addressed how his character, Buck, was supposed to have a cameo in the Doctor Odyssey crossover episode. The actor explained how he'd agreed to the idea before behind-the-scenes changes made it so Athena would be the only character to show up. He said he can make an "educated guess" about what his story would have been had circumstances been different. Check out what Stark had to say below:

ScreenRant: I read that Buck was originally supposed to be in the Doctor Odyssey crossover. Is there anything you can share about what was originally pitched to you?

Oliver Stark: There was no pitch. Well, there was a pitch of, "Would you want to do this?" But no story pitch. I had said yes at the time, but obviously, things moved in a direction where it was just Angela's character. So yeah, I don't know what it would've been. Having seen some clips from the show, I can make probably somewhat educated guess as to what it might have been, but I have no real knowledge, so I'll probably leave it at that.

ScreenRant: That would've been fun. I would've loved to see Buck interact with those characters.

Oliver Stark: I'm sure I would've had a good time over there. Next time.

What Stark's Statement Says About His Scrapped Doctor Odyssey Appearance

He May Have Had More Than Just A Cameo

Buck's current storyline in 9-1-1 season 8 has involved a string of loss, having broken up with his boyfriend, Tommy (Lou Ferrigno Jr.), and losing his best friend, Eddie (Ryan Guzman), who leaves for Texas to repair his family. He was also terrified about his sister, Maddie (Jennifer Love Hewitt), getting kidnapped, with season 8, episode 10 showing her getting rescued. These storylines could have led to his decision to go onto the cruise ship, something Stark hints could have happened in a different way if Bassett wasn't the only character crossing over.

Based on his statement, it seems Buck's appearance in the medical drama would have been more than just a cameo, with possibly a different storyline centering on his arrival. His interactions with the characters in the show could have tied into an entirely different story, something that wasn't just about the ship's vault. Although it's unclear what he would have done, the crossover does signal both shows take place in the same universe. This opens the door for a cameo in a possible Doctor Odyssey season 2, depending on how this first crossover is received.

As of writing, Doctor Odyssey season 2 and 9-1-1 season 9 have not been confirmed.

Our Take On Buck Almost Being In Doctor Odyssey's 9-1-1 Crossover

It Would Have Been Interesting To See Why He'd Show Up

Since Stark teased some differences had Buck shown up on the cruise ship, it's interesting to imagine what reason he'd have to show up there. However, Athena getting ed by the FBI, per info about the crossover, may not have been how the firefighter ended up on the cruise ship himself. Although there's no answer as to how 9-1-1's crossover with Doctor Odyssey would have differed, it certainly would be intriguing to hear what stories had been considered for Buck during its development.
