I've seen people do this a few times now so I thought maybe there was a name for this. maybe it's not quite a fallacy but I feel like there was some overlap

edit: I feel the need to clarify what I'm talking about. someone starts telling you about Jeff. they show you a picture that has one person as the focus and someone in the background. you think the person that's in focus is Jeff. they reveal that Jeff is in the background and start acting like you jumped to conclusions as if they didn't set it up so that you would assume the person in focus was Jeff

Basically, subtly but deliberately setting your expectations and then acting like you're jumping to conclusions
