That's what I was saying. Ren's forcefield wasn't his semblance because Cinder made the exact same force fields in the first episode, and semblances are unique. This means that the force fields are neither Ren's or Cinder's, because they both had them and they were exactly the same, which means it is not a unique ability. Both Cinder and Ren have something other than the force field as their semblance.

Along the same vein, Ren's semblance is not the attack he used to explode the Taijitu's head either, as Fox made the exact same attack in Breach and blew up an Ursa. The Exploding Grimm Aura Technique is not the semblance of either Ren or Fox, as they both did exactly the same thing as each other.
