Jaune actually said he thinks his Semblance was amplifying her Aura. I called it, though I'm not the only one who predicted it would be a "boost" power. Him being able to share was somewhat unexpected prior to the last episode. Could be Weiss has actually been boosted beyond normal by Jaune's Semblance and that affects her summon's power as well. So the reason Cardin hurt his hand punching Jaune is because he suddenly amplified the defensive power of his Aura to the point where it was sort of like punching a brick wall. Real question is how close does he have to be to share that power? Looks as if he doesn't have to be exactly touching to boost someone's Aura so it could be that he is a sort of white mage tank that can boost his entire party's defensive and offensive ability as well as healing the party.
