The sequel is on the same level as the predecessor

[Tree passes out. Carter brings her to the hospital. She regains consciousness and gasps]

Carter Davis: Hey, hey. It's okay. It's just me.

Tree Gelbman: Hey.

Carter Davis: You okay? You really gave me a scare back there.

Tree Gelbman: Yeah. Yeah, I'm fine.

[pause]

Tree Gelbman: You still came.

Carter Davis: Yeah, of course. Why wouldn't I? Oh, we got a hold of your parents. They're on their way.

[Tree is filled with fear, recalling the murders performed in the hospital]

Tree Gelbman: No. They can't come here. It's not safe.

Carter Davis: What are you talking about?

[the lights go out. When they are back, Dr. Gregory Butler is suddenly present]

Carter Davis: [recoils] Jesus...

Gregory Butler: [coldly] Can I help you?

Tree Gelbman: Oh, it's okay. He's a friend.

Gregory Butler: Sorry. Visiting hours are over.

Carter Davis: Oh. All right. Well...

[Carter starts walking away]

Tree Gelbman: Thanks, Carter.

Carter Davis: Yeah. Feel better.

[Carter leaves. Gregory closes the door]

Tree Gelbman: [to Gregory] So, I guess now you know why I wasn't in your class today.

Gregory Butler: Pardon?

Tree Gelbman: Advanced bio.

[Gregory looks strangely at Tree. Obviously he has no idea who she is. He approaches the bed and looks at Tree closely]

Gregory Butler: Uh, I'm sorry. Are you in my class? You don't look familiar.

[Tree realizes it is one of the differences between this dimension and the original dimension]

Tree Gelbman: [chuckles] I'm sorry. My mistake.

Gregory Butler: Right. Well, I'm Dr. Butler.

[Gregory offers a handshake. Tree shakes his hand feebly]

Tree Gelbman: Nice to meet you.

Gregory Butler: Ms. Gelbman, I've been having a hard time pulling up your medical records.

[Tree recalls hearing this line in the original dimension]

Tree Gelbman: I know. I should be dead. My results, they don't make sense, right?

Gregory Butler: Yes. They're highly alarming, to be honest.

Tree Gelbman: Wait. What time is it?

Gregory Butler: [looks at his watch] Uh, it's almost 9:30. Why?

Tree Gelbman: [fearfully] She's about to die.

Gregory Butler: Who?

Tree Gelbman: Lori. He's gonna kill her!

Tree Gelbman: Wait. What time is it?

Gregory Butler: [looks at his watch] Almost 21:30, why?

Tree Gelbman: [fearfully] She is about to die.

Gregory Butler: Who?

Tree Gelbman: Lori. He's gonna kill her?

Gregory Butler: What?

Tree Gelbman: Listen to me. You need to stop her from going down to the OR.

Gregory Butler: [lying] I'm sorry. I don't know who you're talking about.

Tree Gelbman: [sharply] Oh, really? Well, maybe your wife does.

[Gregory looks aghast]

Tree Gelbman: Go.

[Gregory shakes his head]

Tree Gelbman: Go!

[Gregory rushes out of the room. Tree removes the catheter from her hand and exits. She sneaks past nurse Deena at the nurses' station and rushes to Tombs' room. As the security guard comes out of the restroom, Tree hits him on the end with a telephone. The guard collapses, unconscious. Tree bends over him and takes his gun]

Tree Gelbman: Sorry...

[Tree takes the elevator to the floor of the OR. She moves stealthily along the corridor. A nurse appears, and Tree quickly hides in a doorway until she is out of sight. On her way, Tree suddenly notices blood drops on the floor. She cautiously enters the OR, ready to open fire. Following the trail of the blood drops, she moves the curtain. Lori's dead body lies on the floor in a puddle of blood]

Tree Gelbman: [sorrowfully] Lori...

[a Bayfield Baby masked person, armed with a knife, steps behind Tree. She senses it in time, turns back and shoots twice. The masked person collapses. Smiling bitterly, Tree approaches the masked person, removes the mask, revealing Tombs' face]

Tree Gelbman: [snarls] Who set you free?

[Tombs lips move, blood oozes from his mouth, but no words come out. He dies. Suddenly, a curtain moves, and a second Bayfield Baby masked person appears behind Tree. Tree senses the second assailant too late. It grabs Tree, one hand around her throat and the second holding her right wrist, trying to make her drop the gun. Tree struggles, but in vain. She realizes it is the real murderer, who used Tombs as a cover up]

Tree Gelbman: [yells] Who are you?

[the assailant does not answer. Tree notices several cylinders of flammable gas a few feet away]

Tree Gelbman: [enraged] Fine. I go, you go!

[Tree straightens her hand and shoots at the gas cylinders. They explode in flames. Tree and the masked person are engulfed with flames. Tree awakes in Carter's bed, as usual]

Carter Davis: Oh, hey. You're up. I wasn't sure if you wanted to sleep in or not.

Tree Gelbman: [grumbles] I am so done with this shit...

[Tree gathers the group in the lab and explains the situation to them. Then she draws on the board the equations she has been memorizing in the past days]
