Which Experimental Medicine Characters do you like? (Patreon)

I'm curious to know which is the characters in my ongoing story, Experimental Medicine, that you like the most.  If you'd like to add any comments on why you like those interactions in the comments (Or in a private message if you'd prefer) by all means.

It is meant to be a (mostly) first-person story, but I will admit it has kind of slipped out of that POV at times, but I will eventually clean it all up in the long run. All the fun descriptions happen in third person so I can't help it sometimes.

The poll allows for multiple options so please feel free to pick all the characters you like.
