Scarlet wouldn't have dreamed of ridiculing him. Instead she smiled when he was able to bring on the skeletal hand. "I knew you could do it." She would have given him a boost with her own energy, but she was afraid. Afraid that it would make her fly apart again. Or at the very least lose the energy to be able to be visible to even the dead.
She took his hand, with full intent on transporting them both. "It's a wonder you're not dead on your feet. You've been with me all week long. If you were human, or probably even a living god still, you would have collapsed on the the third or fourth day. You just did something no living or deceased person has ever done." It wasn't important to mention they had never tried. She was trying to build him back up. To clean that look of self depreciation off his face. He'd earned a look of smugness.
