Ah, perhaps there is a discrepancy in my understanding of what the seeker is hoping to heal. My thought, when I read Pao's post, was that the seeker was hoping to heal the relationship (and get back together), and in that case, I don't see those two cards as suggesting a rejuvenation or healing of this particular union.
Maybe in a different spread with a different set of cards, the Ace of Wands could signify healing. So, I didn't mean to exclude that possibility of it ever meaning that; however, I don't see it with this throw.
Now, I could see it as the parties healing separately and moving on, but probably not getting back together with one another.
Edited to add:
p.s. I actually posted most of this in the readings thread where Pao posted the reading, and where it is actually supposed to go. If this needs to be expunged because it speaks to a reading instead of a single card, please do so, mods...with my apologies.
