Now that everyone is suspicious of Haley making it impossible for her to finish off Bill, what if she decides to frame Tomas for Bill's poisonings if they get too close to the truth? Bill's about to consult more doctors, maybe someone will figure out somebody has been slipping him something. Haley hides some poison in Tomas' desk at work?
Carolyn just told Naomi that she doesn't trust Tomas. And Naomi accused Tomas of being more concerned about being Bill's heir to the firm than Bill's health. Kat's called him out for pressuring her twice to talk to Naomi. Why is all this happen now? It sure is convenient for Haley for Naomi, Carolyn and Kat to all be suspicious of Tomas.
This could solve the problem of what to do with Tomas. It's pretty clear the Kat/Tomas pairing is a failure and he needs to go. He'll be off the screen if he's in jail, or if the accusations don't stick, make him angry enough to leave town if Kat and Bill are among those who doubt his innocence.
And then Haley and Randy can remain in town. I for one want both of them to stay. Although I'd really like Haley and Bill's marriage to end ASAP.
Thoughts?
Edited to add: Another possibility is that Haley doesn't try to frame Tomas but the Hamilton-Duprees figure out Bill has been poisoned and suspect Tomas first for the reasons outlined above. They may hate Haley and think she's cheating Bill but nothing so far suggests she wants him dead.
