Delano was already able to tell that there was no way that he would be able to keep up with the others. "I'll go as fast as I can," he replied to his brother, "hopefully it will be fast enough." As they headed off towards Hatari's den, very quickly they lost sight of the others as they ran in front.
As much as he hated to admit it, but combined with his healing wounds, lying around endlessly did not help Delano retain his strength from before, and he was really beginning to feel it as he forced himself to keep going, even as he felt himself fatiguing. At least they were getting close to the den, so when Delano caught Muroki looking at him, he ignored the worried look. "I'm fine," he panted out, "we're almost there."
