"Do you think I will go down that easily!??" Rama coughed out blood and he could finally feel the poison that the other Dashavatara had warned. This was no ordinary compound that even he as a hero could remove. Perhaps Siddharta Buddha might be able to do something about it but not at this moment where he had been caught in a bind.
The fact that there were no other Celestial Avatars coming for his aid meant that they too were being kept busy and he would either accept his fate or continue to fight against these puny humans. After all, as much as deadly 'scorpions' could be, they can still be squashed and Rama will be able to escape and retreat to receive treatment even though it would be humiliating for him and unbefitting of the title that he holds.
