Well Firstly Jupiter isn't a fiery planet - it's essential nature is sanguine - Airy in modern Astrology and Sagittarius is an Autumnal sign and a common (mutable) sign, so is the least 'fiery'. So don't expect the fieriness of Aries. or even Leo.
Even more important the Ascendant whilst important is not the only determinant of Temperament - Sun and Moon and their rulers and signs are also important - in his case it's a November birth, which is Autumnal and injects some Melancholy into the Temperament and the Moon is in it's last quarter and injects some Phlegm into Temperament. These don't change with relocation, the birth is still Autumnal and the Moon phase is still fourth quarter. The Sun is still ruled by Jupiter and the Moon is still ruled by Venus - only the Ascendant will change, in this case weakening the fieriness by removing Mars and replacing it with the airiness of Jupiter.
As I didn't hear her reading either I can't comment any further on what she meant or didn't mean - it does look as though she had ideas related to the Nodes but what they were I can't say.
If you're looking for a way of reading the future there are many. Both Dave and I would use Solar Return charts, I would also consider Primary Directions and Profections. Dave adjusts his Solar Return charts for precession and has a very well developed approach of 'progressing' his Solar return chart on a day by day basis, which yields very good results. Many Astrologers use Secondary Progressions (based on a day for a year). Transits in all approaches are really the bottom of the pile - the last thing you look at and the least globally important.
I've not by any means been comprehensive there, there are many more techniques used for predictions. It's one of the most difficult areas of Astrolgy, not because the techniques are inherently difficult but because there are so many of them and at different levels of analysis that setting up a systematic, coherent and internally valid approach is not easy. I struggled with this for quite a long time.
You specifically mentioned and showed interest in progressions. The most frequent approach is to use secondary progressions based on a day for a year. Now you don't actually say or presumably know whether this was the method she actually used. Basically this approach says that the first year of your life can be read from the chart for the first day (which is of course your natal chart). Detailed readings for other years are from the relevant day of your life. So if you want to make predictions for your 25th year (i'e' from your 24th birthday to your 25th birthday) you take the chart for the 25th day of life (you count your day of birth as 1) and cast a chart for the birth time. The location is almost certainly the same but even it has change there are some who would argue that changing the location is a mistake - and I don't disagree with that).
Now a progressed chart can be advanced at a predetermined rate to allow any day in that 25th year to be identified and examined. In your case a secondary progressed chart for today shows the Moon in Leo in the second House. Now the Moon's position by sign looks right to me, given that it completes a return to it's natal position every 28 days approximately. (i.e. your progressed Moon will be back at it's natal position around age 28, 56, 84, etc).
The rate at which MC and ASC change is more debatable and there are a number of ways of working out their progression rate and that Astrologers have argued, argue and will continue to argue the merits of these is a bit or an understatement LOL. However again I can't get one to produce a fourth House Moon in the several attempts I've made but perhaps a night of chart casting might hit on her method
However a transit chart for the day and time of the reading may have had the Moon in the fourth House. What methods she was using should have been explained at the time and she should have given you both the charts and a written report so that you can review her reading at a later time. It's unreasonable to expect your to be able to take it all in and remember it.
OK Next set of questions ;-)
