yeah, there's a third tape in one of the school lockers under the name Logan. You look at a document (if I remember correctly on the teachers table in the kindergarten room which has "LOGAN (with a combination to the locker)" scribbled on it). I'm guessing looking at this document after looking at the two tapes unlocks the locker automatically cos I opened it after I left the room. Its how you can confront her about her being from Crawford with evidence. In the video it shows the doctor zipping up his pants
and her adjusting her clothes and then him saying they need to cut this deal off cos the higher ups are now checking how much supplies are in the safe. She gets vex cos shes getting the meds so she can keep the rest from finding out her sister has diabetes, which would get her kicked out from Crawford. Therefore, this is why she went ham on him in his zombie form cos her sister did get chucked out in the end and he basically fukked her and her life for nothing
