2-1B-D3, or "Beedee-three", is a 2-1B medical droid.  It has masculine programming and its bedside manner varies, according to its patients' attitude, from 'efficient' to 'outright hostile'.  It treats its charges well physically despite being somewhat 'testy' and is often heard telling patients to 'take care' and 'don't be so ready to die next time'.
