That one was simply Disney meddling with the budget. Apparently since Cruger was a Ranger, and a "sixth one," they weren't given enough resources to provide a full time actor for Omega/Sam's actual role, as Disney thought six Rangers was a suitable "quota". This would have been fine, they'd simply try to write out Dekabreak's episodes or footage and shift that potential "focus" to other characters (See Sky taking a part of Tetsu's role in "Reflections"). But due to the high amount of appearances of the character in the source footage, and Bandai's likely insistence to include him in the show, they had no choice but to go for the most budget saving contrivance they could get to make it "plausible." They'd still try and write around him though, leaving Sam with (outside his introductory episodes) no real character focus or emphasis other than "another Ranger to add to the team, who appears in fights, and eventually leaves at the end." Kalish and the other writers are still quite frustrated at how things ended up and wish they could have handled the situation better.
