Makoto desperately states 'I have to get out of here. I have to get out, right now! I need to make sure everyone's safe'
saiyaka overheard him and inquired 'makoto? make sure who's safe?'
Makoto decided 'i need to come clean about this! ok saiyaka this is the video with my motive on it watch carefully and you'll see who i was worried about ' (after the video ended a second time)
Saiyaka is extremely traumatized
'that's horrible! that bear made it look like he had killed your parents and sister!' so she decided to become makoto's accomplice in killing toko Fukawa and take the blame allowing makoto to leave to check on his parents and sister the end
