The punch was not what any of them expected. Remey had been practicing with the different elemental affinity knuckles a little but not as much as she could have. She had been too focused on the alchemy side of her system to truly grasp the real effects that came with the elemental knuckles.
Therefore, when the flames that were on Midnights' torch jumped to Remey's fist and the crack of the ice multiples, everyone was shocked. Even Remey. The shard of centennial ice that fell was much larger than they expected. The spiderweb of cracked ice left behind was also a good sign for what their next hits could bring.
"You just punched with fire! Fire!" The excitement Gil had was more than Remey had at the moment. She had not expected the attack to be used this way and she had been unaware that she had even learned a new skill related to punching.
