Nagi in Manshine Vs Barcha Theories

Just wondering what are people's theories on how Manshine Vs Barcha match,

Do you think Nagi will evolve in some way? Do you think Reo will evolve in some way? Will Nagi discover his flow mode in some way? Will Nagi and Reo work together? Will Bachira win against Nagi and Nagi will be abandoned from the story?

My guess is that Nagi will awaken his flow mode. It will be something about laziness the way Rins flow is about destroying things but I am not really sure what his ability would be. Maybe some form of being able to score in the box in any way the way Shidou does. I feel like Nagi could also just control any ball there and avoid the people guarding him and score.

I don't really know how the Nagi learning soccer and strategizing part would work out like I don't think it suits him. His development could be about how he goes back to being lazy and just does not do much in the field and then suddenly appears controls the ball and scores and kind of like disappears for the remaining time
