Sebastian "Seb" Grayling is an F1 junior doctor who worked in the emergency department of Holby City Hospital from October 2016[1] to January 2017.[1] Coerced by his father into a career in medicine, Seb joined the department nervous and eager to please his colleagues but was only put-off by his father's frequent visits. On New Year's Day in 2017, Seb left the department shortly after withdrawing an allegation against Dylan. Dylan also secured him another placement at St. James Hospital, so he could have the opportunity for a fresh start.[2]
