I don't really care what the situation or reason is, I just wanna see Gladio being protective over Noctis or making it clear that to hurt Noct you have to go through him first.

Can be kid!Noctis getting bullied and kid!Gladio stepping in and putting the bully in his place. Can be Gladio taking a shot meant for Noctis and almost dying. Can be Gladio literally shielding Noctis from a spell or gunfire with his body and still fighting after. Can be someone hitting on Noct and Gladio squaring up to them.

Would prefer gen but free reign apart from that! Please give me Noctis being threatened and Gladio taking his role seriously!
