Ok i got it working, while i couldn't get the cutscene for kevin going into the school, i could reset score with Rebecca, give myself the video and it had to be when Rebecca was showing me the homework which gets her relationship points to 25 which is when i could finally share the video. no idea what was going with kevin but im good now thanks.
tho i just remembered 3 things; 1: where do i find out about strong cocktails for Janice in the pool at night, and 2: how do i get Emma to help me with the hospital cause she keeps saying she's never had time. 3; how do i mess with Rebecca's husband's car? i saw a clip where you could tamper with it to get her to walk through the part but i dont know how to get the shady guy to sell it
