That's why AJ told Carly, "For Ava..." for a reason so Carly will have to investigate on that and be like, "Why did AJ attack Ava? What reason did he do that?" So I AM HOPING that's what will lead her to find out the truth when she investigates on that and I am so glad that she and Ava are no BFF so she will have no reason to protect her ass this time and have no problem spilling it to Sonny in no time but if she does keep her secret for her, well, secrets have a way of coming out anyways.
