I think Kaz+Bree wouldn't really work. That's just my opinion tho. Bree and Oliver were pretty cute together in Lab Rats vs. Mighty Med, but Oliver and Skylar are totally soulmates <3
Chase has no lasting love interests sadly, and Bree was single for all of EF.
Yeah maybe if there had been a season 2 she would have got a boyfriend. I feel like in Elite Force Oliver is kinda a creepy stalker to Skylar instead of adorable admirer. They would have made a really cute couple still
