Coulson takes the opportunity of her unconsciousness to kiss her forehead and promise her that he’s still with her, protecting her. Waking up a moment later, she tells the other agents that for a moment she thought she saw her Phil with them, but it must have been a dream. They corroborate/gaslight her into believing that her senses were wrong, which is just a little creepy. Especially for somebody who the police refused to believe when she reported her stalker, and whose foundation of trust in SHIELD and Coulson is based on the idea that he would never lie to her or be part of an organization that lies.
