Some moments later...
Will: "Excuse me, sir?"
Mike and Y/n: "Excuse me, sir?"
Agent Wallace: "What?"
*Y/n gets nosebleed and a vision: Agent Harmon gets shot*
Will: "We're hungry."
Agent Wallace: "I could eat."
Y/n: "I'm right back..."
*Y/n walks in the bathroom and closes her/his/their eyes and gets nosebleed and sees Max, Lucas, Steve and Dustin*
Max: "I know you guys are staring at me."
Steve: "What...sorry?"
Lucas: "You said you needed something?"
Steve: "Just hanging up."
Max: "How you think your eyes boring into the back of my head is protecting me from Vecna, I don't know...."
*Max walks to them*
Max: "You can look at me now."
Dustin: "Thank you."
Lucas, Steve and Dustin: "Sorry..."
*Max gives everyone a letter*
Max: "For you. For you. And...umm...you. Oh and ummm...give these to Mike, El, Will and Y/n. If you can ever get a hold of them again...What are you doing? No...don't. That's not for now. Don't open it now. Don't...Okay."
Dustin: "I'm sorry...What is this?"
Max: "It's...ummm...it's a fail-safe. For after. If things don't work out."
Lucas: "Wait, whoa...Max, things are gonna work out."
Max: "No! No, I don't need you to reassure me and tell me it's all gonna work out. People have been telling me that my entire life and it's almost never true. It's never true. I mean, of course this asshole cureses me. Should've seen that one coming."
*Y/n appears in front of Max and Y/n hugs her*
Y/n: "Hey Max.....we'll kill Vecna and you...you are not going to die...okay? I would never let that happen..."
Steve: "How...where...what...?"
Y/n: "Long story...but I need to go again..."
Lucas: "Wait...the letter."
*Lucas gives Y/n the letter from Max*
*Y/n closes her/his/their eyes again and gets nosebleed and appears in the bathroom again*
Y/n: "Yes...I can control my powers"
