In episode #15, Misato and Kaji are seen flirting quite a bit during the wedding party, with Ritsuko noting as such. This ultimately culminates in the kiss later in the episode, but before this we have the following:
Misato rings Shinji from the party to let him know she will be late home. Shinji is unconcerned, Asuka however...

Asuka: Was it Misato?
Shinji: Yes, she said she'll be late, so don't wait up for her.
Asuka: What? Don't tell me she's coming back in the morning!
Shinji: No way, she's with Mr. Kaji.
Asuka: What are you, stupid? That's WHY!

Shinji cannot conceive of any impropriety where Kaji is concerned, but Asuka is decidedly more cynical. Immediately following Asuka's words, we have a very quick cut (The number is 15_C181) of two silhouettes -- Misato and Kaji -- at one end of an alley.

Note in particular that in the background a train can be seen and heard loudly rolling by. Here's a short clip of the scene where the sound can be heard.
This is a very rapid cut, and it's not initially clear what's going on. On first glance, given the context and muffled sounds, it appears as though Kaji and Misato are engaged in sexual intercourse in the alley. However, immediately afterwards, we are told that it was "only" Misato throwing up.
Episode #15 Alley explanation wrote:
[wkimg]15_C183b.jpg[/wkimg]
Kaji: You shouldn't be throwing up at your age.
Misato: So sorry I'm that age.
So ostensibly the quick alley cut is explained, and any other interpretation the audience may have had can be dismissed as a result of their over-active imaginations, not the artists intent.
However...
Later in episode #25, during instrumentality and the Case of Misato Katsuragi, Shinji witnesses a flashback to Misato actually having sex with Kaji.

Ritsuko: Is that why you slept with him?
With that man?
Misato: No, I slept with him because I loved him.
[wkimg]25 C211.jpg[/wkimg] [wkimg]25 C212.jpg[/wkimg]
Misato (child): Did you really love him?
Misato: Yes, I did.
He accepted me for who I am.
TEXT:
"Really?"

Misato: He was kind to me!

Misato: No! Stop it! Don't show this part of me to Shinji!
Just to be clear: Shinji really is witnessing a flashback of Kaji and Misato having sex here. We have the quick sequence of pixelated flashing images, themselves taken from Misato and Kaji's post coital chat at the end of Episode #20. Moreover, since this scene is revisited in the End of Evangelion. where there is far less ambiguity about what Shinji is seeing, we can be fairly confident about what is being alluded to here(Even without noticing Misato's cigarette box). Misato's words about Kaji being "kind" are simply a euphemism.
However, while Shinji is shown watching this flashback, a series of harsh train sounds can be heard in the background. Again, here is a clip of the scene showing these sounds.
The train sounds here are also being used as a euphemism, mask or metaphor for the more explicit sounds heard in #25' (A train is heard, but only very briefly in the EoE version of this scene). But this use of the sound of a passing train sound as a mask or aural misdirection for sexual intercourse raises questions about cut C181 way back in episode #15.
[wkimg]15_C180.jpg[/wkimg] [wkimg]15_C181.jpg[/wkimg] [wkimg]15_C182.jpg[/wkimg]
In light of episode #25's use of train sounds, what exactly are we supposed to make of the quick alley cut in episode #15? Is it supposed to simply depict the result of Misato's overdrinking? Is it an instance of the creators deliberately titillating the audience through misdirection? Or is this clip a euphemism for something that was likely going to happen in the alley before Misato's stomach got the better of her?
I'd like to hear people's opinion on this. We earlier have an emphasis on Misato's improving relationship with Kaji at the wedding party, Asuka's blunt appraisal of the evenings likely outcome, this quick alley cut of Misato throwing up, with this itself followed by Misato and Kaji's more mellow "romantic" starlit walk culminating in their kiss. Does the cut really makes sense in the midst of this? What is its purpose? Does the train have anything to do with things, and most importantly if so, are there any other similar instances of this aural trope/allusion in the series?
