Picking up where we left off, after Quentin cuts off Alex, Alex continues with, "For chrissakes, Quentin, listen to me! Now she's at my place right now." - though the subtitles have -

- with "chrissake" rather than crissakes, and "Now" missing from the beginning of Alex' second line - however, the entire first line is missing in the closed captioning and all that appears is -

- also with the beginning "Now" missing - And after Alex basically tells Quentin as scripted, "Now you've got to get out of this house!" and "Quentin, all you have to do is come with me --" and "Tracy understands." - and after Quentin then asks Carlotta, "Where's Mrs. Collins?" - and after Carlotta replies, "Well, I'm sure she's in her room",  the closed captioning acknowledges a sound as -

- though the subtitles do not - and then Quentin goes running up the stairs calling to Tracy - though interestingly enough we do not see Alex start up after him...

And getting back to that sound that the closed captioning acknowledges as a door closing, it's interesting that a sort of snapping sound is heard after Alex says that Tracy understands - but that sound isn't acknowledged. And after Quentin whirls around and calls out to Tracy after the supposed door closing sound, are we to presume that sound is what makes Quentin whirl around? The script doesn't indicate that there was even supposed to be such a sound. And as I said, the subtitles don't even acknowledge it, though that may hardly be an indication of anything because, as I've said many times already, the subtitles are quite picky when it comes to which sounds are and are not acknowledged.

Perhaps it's up to audience members to make up their own minds:
