When the celestial energy activates inside Quinn, his veins would glow red as the energy begins to pulsate inside of him. Also, even after transferring the celestial points to the others, Quinn would have enough energy.
However, for some reason, even now, he still couldn't use this celestial energy in the same way as he had done in his fight against Graham. In simple words, he couldn't use it externally and only felt it pulse through his body. But, unlike the others, his body didn't change in appearance either.
Quinn had a few guesses as to why his Celestial energy was reacting as such. Perhaps he needed to increase his Celestial Level, or there just wasn't enough energy in him right now. Regardless, this was something that he was sure Russ wouldn't be able to copy.
