Okay so I decided what needs to happen in season two of Daybreak.
Josh and Victoria have weekly hangouts where they chill and the mall and sign. Mostly they just tell each other what is up with their groups because the Cheermazons and the Daybreak kids are an awesome alliance and have each others back while remaining separate groups.
Only one day Turbo comes across him and decides he wants to learn ASL partly because he knows it would be easier to communicate at least with Josh and Victoria...plus he likes the idea of being able to tell Wesley that he loves him in another language because he is a huge sap. While Josh wishes he could be a little hesitant at the idea, Victoria lights up at the idea of another person she can communicate with so Josh agrees. And to Josh’s surprise Turbo takes it very seriously even though he gets frustrated a lot, thankfully Victoria can be scary and just glares at him until he calms down.
Of course once Wes finds out about Turbo learning to sign he asks Josh to teach him too. Because even though he speaks Turbo he wants to support him in any way he can (at least in the nondestructive things).
Soon it gets around and everyone starts having bi-weekly meetings learning how to sign (one with the Cheermazons and one with the Daybreak kids...though everyone is welcome at both). And outside the meetings Victoria helps the Cheermazons and Josh helps the Daybreak kids. It ends up becoming super handy when they have to go exploring because then they can all communicate with each other without talking.
Each kid ends up having their own favorite sign they use most.
