When Cardin was beating Jaune up and a bright white light flash, and then Cardin was on the ground and Jaune was still standing, that was our first glimpse of Jaune's semblance. A lot of us theorise that it is a rebound/reflection semblance that reflects the damage back on the attacker. A bit inaccurate. Cardin was standing, and he had dropped Jaune onto the ground.

Cardin was cradling his hand and crying out like he was in pain.

In the volume 1 director's commentary, Monty said that was the first sign of Jaune's Semblance.
