Not going to read through all 16 pages, but in case this wasn't mentioned: Cersei keeps wondering if Jaime will return. More than a few times did she keep the thought fresh in her POVs in TDWD. Therefore, I am willing to bet that he does come back, but with the intent to kill her. That, or at least he'll be against the Iron Throne. It's possible that fishing for one of unCat's daughters is another likely scenario.
