You need to use your flashlight to get past Elina.
After the tape ends, the room goes dark and you will need to keep an eye on both Elina and the ghost hands that pop out of the mirror. Just flash your light a couple times until the ghost hands appear, but do not take too long or flash too much, or else both will trigger her jump scare. For a little bit of help, I kind of did a little something that I would refer to as like the “Peek-a-boo” method: Simply turn off the light for a couple of seconds and then turn it back on a couple of seconds and repeat this process until the ghost hands appear on the lower right and left of the mirror and then click on one of them. Do this thrice and the interview with Elina is done.
Here’s how I did it if you need help:
The time stamps of the successful attempt of Elina’s interview and the method I used are from 6:59 to 7:58.
