Surprisingly, yes. Jace Mitchell and Gabrielle Oak, not because they are one of the so called cutest couples here but because of how their relationship started and how it will ultimately end. We all know Jace left Melanie after two years of commitment for Ms. Oak and it looks like Gabrielle might be leaving Jace for Mark or some other guy she sets her eyes on. 

What people aren't aware of is that Jace and Gabrielle were in a relationship before he ended things with Melanie. He cheated and it's only fitting that Gabrielle is now the one doing the cheating. Jace will get a taste of his own medicine and I'm just waiting for everything to crash and burn around them.
