What happens if you watch the ring while hooking up with someone with the it follows std? Do they team up against you? Or do they fight for winner takes all?
There is a sadako vs kayako movie, basically The Ring vs The Grudge, and from what I gather the curses can combine into an even bigger curse. On the other hand in sadako vs bunshinsaba (the Red Lady) they basically just brawl until they're both trapped forever.
I get the feeling that the It Follows creature would suck in a fight, but it would make for an excellent post credit scene where it walks into a well.
The curse transfers if you record the video and make someone else watch it. It doesn’t transfer back like in It Follows. You just have to show it to someone who is on hospice. They will die horribly, but they were going to die anyway.
