The disciple was there:
The Hater, startled, put down the gun, and fled the scene quickly. The Disciple, depressed as usual, fled the scene too.
The hater and the disciple are not in the same class:
"See you tonight. Today's gonna be as sweet as pie." The Hater grinned and walked into class. The disciple walked away until she stopped, and turned to theirs.
The disciple's sex is female, but they may very well be using a male name:
The Disciple shot the Hater a death glare. "For the last time, don't ****ing use those pronouns on me. I'm gender neutral, alright?" The Disciple folded their arms.
Also, it was stated that two people would be set to die each phase, but there only seems to be one in danger this time around. There are only two people left that haven't been targeted, and one has to be the disciple.
If universe was the last disciple, it would have been stated since we have a phase to find and kill the hater before they find a new disciple.
