Wilton is a doctor in Afterlife.
Doctor Wilton was called by Jiaying after the leader of Afterlife refused medical attention from S.H.I.E.L.D. following sustaining a gunshot wound when she was in negotiations with Robert Gonzales. While Skye, Lincoln Campbell, and Jiaying talked, Wilton removed the bullet fragments from Jiaying's shoulder and stitched her wound. Skye asked Doctor Wilton if Jiaying needed a blood donation, but Campbell started arguing again before Wilton could answer.
