And picking things up with the next scene in the script:

148    INT - MASTER BEDROOM - NIGHT                        148        CLOSE ON TRACY as she lies in bed sound asleep.  HOLD        until she stirs, then WIDEN to reveal she is alone.        Through the window in the B.G. the tower can be seen.        A light glows there.  Tracy opens her eyes and,        noticing the light, she gets out of bed and crosses        to the window.  TRUCK IN ON HER as she tries to decide        what to do. 149    INT - STAIRWAY TO THIRD FLOOR - NIGHT              149        as Tracy comes TOWARD CAMERA PAN WITH HER as she        crosses to the tower stairs.  HOLD ON HER BACK as        she climbs to the door.  Hesitant, timid, she knocks.        THE SOUNDS OF MOVEMENT can be heard inside.                              TRACY                  Quentin!        There is no answer.  She raps harder.

And that's when Tuesday's first quote -

Page 70/Scene 149 - Tracy: 'Quentin!'

- comes up, followed in the script by:

The door suddenly opens, revealing a seemingly drunken Quentin staring down at her.  Past him she can see the rumpled cot.

And that's when Tuesday's second quote -

Page 70/Scene 149 - Tracy: 'I...I thought you weren't
coming back here...'

- comes up.

And when it comes to what's different with the dialogue, Tracy actually says "I...I thought you said you weren't gonna come here anymore..."

And when it comes to what's different with the descriptions and directions, in DC's script he's added to the setting on Scene 148:

INT - MASTER BEDROOM - NIGHT - FROM WINDOW SIDE

And right below that he's also added:

148A   P.O.V - TOWER

However, he doesn't make any changes to the descriptions, so it's interesting that his Scene 148A doesn't begin close on Tracy as she lies in bed sound asleep - nor does it hold until she stirs, then widen to reveal she's alone - and neither is it the case that through the window in the background the tower can be seen - and all that is because the scene actually begins with a shot through the window with the tower being seen with a light coming from it - and after that we do not see Tracy opening her eyes because when we see her her eyes are already wide open. And considering that so much of how the scene is scripted to open is not actually in the film, it begs the question of whether or not the background music in what is seen of Scene 143 is cut so short because at one time Scene 148 did open as scripted but, as a part of the enforced editing, what is missing was cut for time? But whatever the reason for the abrupt ending of the music is, from the point we see Tracy with her eyes open, Scene 148 plays as Tracy gets out of bed and crosses a few steps to the window - however, the camera doesn't truck in on her as she tries to decide what to do because Scene 149 begins immediately after that - however DC made changes to that setting, too:

3RD FLOOR LANDING INT - STAIRWAY TO THIRD FLOOR - NIGHT

And right below that he's also added:

149A   INT - LOWER TOWER

So, it will probably come as no surprise that things here don't exactly begin the way it's scripted. How things actually play is that in Scene 149 and shot from the 3rd floor landing we see Tracy coming up each section of the stairs -

and then she hesitates a few moments as she looks at the third floor ahead of her -

- and then after having moved closer to them, Tracy hesitates for just a fraction of a second -

- before making her way to the tower stairs. And then when it comes to DC's Scene 149A, Tracy isn't seen ascending the stairs from behind but rather -

- from her front - and after Tracy knocks on the tower door for the first time, we don't actually hear the sounds of movement from inside - in fact, when there's no respons from her second knock, she actually turns away from the door -

- and is about to start down the stairs before Quentin opens the door -

- and stares down at her - however, Quentin doesn't seem as if he's drunk - and after she brings up that Quentin had said he wasn't going to come to the tower anymore (and I do love the nervous little smile Tracy shows before -

- she mentions that), it doesn't appear that Tracy somehow sees a rumpled cot. We certainly don't see it.
