Lincoln Campbell had joined the Agents of Shield relatively simply. He fit in with the group, and had a 'thing' with Daisy. When the bus picks up an undercover agent Lincoln recognizes the girl, a blast from his past. 'He hasn't seen her since they were 19, young children just trying to understand their powers. They had promised each other friendship, and she had disappeared without a trace. Yet here she was, fit, confident, and a Shield Agent. She seemed to not recognize him, but he could never forget her piercing eyes and the small scar on her lip. He remembered every part of her, and could never forget.' In flashbacks, confrontations, and near-death experiences Lincoln and Adira remember who they were and find out who they really are.
