Time is not running against the clock anymorethe session not fixed to 50 minutesbut against the weave in the analysand's discourse. It's instead the time of the unconscious. If it sways over the duration of the analysis each session should include the very end: an end that triggers the becoming of an analyst.
This tenor of things likely to work in opposition to the various techniques in search of awareness, through interpretation as do you realize what you are telling me? or the like, fairly corresponds with the Freudian Nachträglich, retroaction already present in a day-to-day basis. You can understand a phraseıs meaning only afteraprès coupit is said.
Again the schema of retroaction is in turn the schema of traumafor there to be trauma you need two instances. Let's look into the trauma par excellence, the trauma of castration.
In the first instance the boy, over infantile masturbation, hears real castration threats. Those words, the very ones he heard, are bound to start up anxiety when the boy later confronts the lack of the penis in the woman (in the mother), that is when he confronts castration in the Other. Here then is the second instance, for the case lurking in the effect of threatthe effect of threat will acquire additional sense whereas the first experience gets resignified.
As for Lacan's proposal of punctuation: After the Freudian Oedipus the point de capiton gets inscribed when the inclusion of the Name-of-the-Father in the Other conforms with the emergence of the phallic signification; and this is what gives sense to the phallus' sexual undertone.
Inside the individual's story enigmatic points condense the certain way that hints at an inflexible jouissance. This allows for one of these points to return at all times in the discourse. It returns relative to compulsion while emerging in the subject's talk to the Otherthe analyst. Apparently nonsensical to him, the point is nevertheless an enigma and as such meaningful. The subject will then start to bestow sense upon the actual event, as to later endow it with another sense, and still later with yet another sense...
In analysis words lose their meaning. If the experience is bound to bring up different interpretations of the same event, provided other diverse signifiers come to adjoin new meaning, it's on behalf of and because of its correlated signifying character, "structured like a language."

Lacan speaks of resubjectivation and restructuration.
The example he puts forward is the analysis of the Wolf Man, insofar as it produced a series of retroactive restructurations relative to an event, fundamental for him, the primitive scene of anal coitus. And this is what allows the subject to draw on his story, to include in it his own participation a story reconstructed throughout the talk with the analyst, hence its various rectifications.
The cut of the session is in itself a mode of interpretation, an enacted interpretation that will speak for itself, "...it can't be indifferent to the weave of the discourse and it corresponds in the session to the role of a scansion; as in poetry, it precipitates concluding moments."
