Nick and Caroline?

she even went to jail for it; remember, Bo had to arrest her.  Nick knew all along that Caroline was innocent of the crime.  Here’s what happened:

Melanie and Trent were talking right near the late Shawn Brady’s grave in the cemetery. Trent had business deal lined up but wanted Melanie to close the deal by having Melanie have sex with the other person in the deal. Melanie and Trent argued and he knocked her down causing her to hit her head on a headstone leaving her dazed. Nick who was hiding in some bushes then killed Trent by stabbing him in the back. Trent fell on Shawn Brady’s grave with a knife sticking out of his back and Nick ran off. A minute or two later Caroline Brady arrived to visit her late husband’s grave and found Trent lying dead. She pulled the knife out of his back because she thought that Max who had threatened Trent had made good on his threat.

Before Caroline could do anything else two uniformed Salem PD cops showed up because someone had reported Melanie screaming during her encounter with Trent. Caroline was arrested by Bo and Hope for murdering Trent because she was found with the murder weapon her hand. Bo and Hope took to the police station in handcuffs where the met Roman who was beyond shocked at the site of Caroline being under arrest.
