About the Corporal[]
When Hawkeye and Dr. Anthony Borell, a visiting civilian Army consultant, arrive at the Battalion Aid Station, to aid a wounded surgeon there, they are forced to cooperate on a difficult operation in the field, where they are assisted by Jarvis. In spite of the initial friction Borelli and Captain Pierce were then heading to an aid station to perform surgery on the wounded soldier. When they both get at each other's throats in preparation for surgery,Corporal Jarvis then arrives in the latter part of the episode for the surgery. Jarvis quickly comments on the friction between the two surgeons, wondering why they couldn't put aside their bickering and get to the work that was direly needed; his comments forced the two to focus on their needed surgical expertise, and partly because of his comments and in spite of the two both suffering broken wrists in the midst of heavy shelling, they are able to get through the long session together, as "Righty and Lefty"!
