He wouldn't have had enough time to draw a seal on you, so he probably used a mind jutsu on you to block away the memories..." Of course half-way through that he'd switched into his 'analysis/report' mode as he liked to call the way he acted when he started to talk seriously in the middle of an explanation. "He was probably at least part Yamanaka, since they're the only ones with the capability to directly access your memories."
