In *Terminator: Dark Fate* Dani-commander in 2042 arranged for Carl's GPS coordinates to be burned on Grace's body (before sending her back in 2020) and told her to go there in case she needs help.

Assuming that the events in 2042 belong to a slightly different timeline (in that Dani-commander did not actually have to be saved from the Rev-9 22 years prior), how did she know about Carl?

Is it assumed that Dani-2042 somehow have met Carl in her past and so in that he had a different story to what was shown in the movie?

Disclaimer: I am not holding my breath regarding Terminator time-travel stories (like any other time-travel) making consistent sense. After all, time travel back in time is neither eventually/logically coherent nor even theoretically possible. But I am just questioning what could possibly the creators of the movie expect the audience to think on this question, if anything.
