If doctor is the serpent, Soldier At-tan once said that "he's just taking his time to digest her".
But at the same time, he's always associated with the Rod of Asclepius because, well, he's a doctor.
Looking at snakes symbolism, they have been used so much in symbolism that they have come to symbolize both good things and bad things in a lot of cultures...
I wonder how it will turn out. I don't doubt Doctor's kindness, but... I am still a bit perplexed because of Soldier At-tan words...
The text and the drawing at the end are beautiful btw :)
