If I had written the TJ, one thing I might have done was have Ciara disappear under mysterious circumstances, with Ben fighting to clear his name, as everyone in Salem believes he has murdered her.
There would be flashbacks aplenty, displaying the cracks that had formed in Ben and Ciara's relationship over the past year. Perhaps Ciara had returned to school, and Ben was jealous of her new friendship with a male classmate (Evan?) and had stopped taking his meds.
We might see some of the subsequent trial, too, as Ben's attorney fights to keep his "prior bad acts" from being entered into testimony. Ben would ultimately be found guilty and sentenced to life for Ciara's murder, even though authorities have yet to locate her remains.
However, there would be two major twists:
1) Jordan, who maintains her brother was not involved in Ciara's disappearance, is actually the mastermind behind it. She arranged for Ciara to be kidnapped in order to keep her away from her brother, and then made it look like she might have been killed.
2) Jordan's co-conspirator is none other than Hope-as-Gina, who is forced into participating after Jordan figures out that Gina has taken control over Hope's mind and body. In exchange for Jordan's silence, Hope (or Gina) has hidden Ciara away.
But, when Jordan's ruse is inevitably exposed, Ben is exonerated and reunited with Ciara, he discovers Gina and Dr. Rolf have succeeded in erasing all memories of him from her consciousness. And this time, when Ciara learns all about Ben's past, she might not be so inclined to fall in love with him again.
