I am still confused about subpoenas in the Jones vs Abel lawsuit

I am still confused about all of this. Can someone kindly explain how the subpoena process worked in that lawsuit?
What we do know thus far is...

In Aug, the following happened: Jones confiscated Abel's phone. At some point, still in Aug, Lesley called Nathan and said she saw her texts and she will be sued.
Did Jones get a subpoena afterward to legitimise the texts, for her to add them to her lawsuit in Dec? Can you get subpoenas before a lawsuit has been filed? Or are there other contexts I am missing?

In Towhey's emails to JB team, she says: The complaint includes extensive private text messages and emails she obtained through a subpoena that document the crisis communication operation.
Did BL team mislead the NYT by saying they obtained the texts through a subpoena?

Lastly, a few more follow up questions about subpoenas:

  1. Can you share information you obtained from a subpoena to a different party? Under which conditions are you allowed to do that?
  2. What happens if you share manipulated text, which someone then uses in their complaint or news article?

Where is the subpoena? Albertson and Davidson (at around 25:30 they discuss this issue. Mystery not solved).

Edit: Typos (probably missed a few. Apologies)
