"I let my brother go to the devil in his own way." - The Strange Case of Dr. Jekyll and Mr. Hyde

See that face of concentration as the 

noble veterinarian transplants a new heart, 

and resuscitates his stuffed monkey;

in an anxiety filled, life or death moment?

 See how cute and sweet the veterinarian and his assistant are 

when their diligent efforts pay out?

 That is what I saw.

I was not witness to

the character transformation taking place
 as they worked on the stuffed dog.

I only happened across the sinister twist an hour later.
