Agree with you, she already has enough to contend with, don't add any negative news.
The horary chart is normally valid for the upcoming future, but because things can change, people have free will to act, the situation can shift, and a new chart would reflect the new situation.
For example, we have doubts about the lawyers she has to defend her, if this changes, the whole picture could change.
"This 12th house is ruled by the sun, which is domiciled, and thankfully not in the 12th house. "
This is related to the current chart, and remains this way. You can't progress the chart, It doesn't quite work that way.
When you write that your friend will try a different defence tactic, that could be a new horary question, as it will change the current situation.
Keep us posted, please.
Sorry about her partner, she is lucky to have you as a supporting friend.
