For York, I was thinking that he'd probably recall sitting in the backseat of an old beater car on a long Sunday drive with his parents. (I was also thinking that he might be peripherally aware that there was someone in the backseat with him, but, since said person isn't the focus of the memory, he'd just be a vague shape instead of an actual important presence. Of course, if this is too much for the first session, I'll forgo it for just the memory of the drive in general, maybe also remembering some bit of song from the radio and his mom singing along with it)
