David introduces himself to Sangeun, the Korean patient. David explains to Sangeun that when the plane shook, it shook so hard that it ruptured her corneas. Sangeun is very confused and afriad as David tries to explain to Sangeun about a cornea tranplant, and shouts at David to "find someone who's actually Korean." David leaves. Sangeun apologises to David for her behavior earlier, and that she understands her situation now. Then Sangeun askes David how he knows Korean.
