In the middle of the discussion, Lodi presents several strange memories and visions. Lodi speaks of different occurrences from various points in time: being at the outskirts of a small town in South Dakota in the year 1960 or watching a biplane in Wisconsin back in 1929. Lodi states that their connection with the Nine has shifted, and they have begun learning to control the abilities that had previously controlled them.
As the conversation continues, Lodi tells the Guardian that they have seen endless moments from different times in the past and even some from the future. Lodi promises that they are not leaving anytime soon and that they will meet another day. The sequence concludes with Lodi saying something about continuing the cycle, thus ending the secret story arc. At the end of the dialogue, the Sortie Sendoff side quest concludes, unlocking the ending cinematic associated with the Moment of Triumph event.
