Did Ventus figure out that Terra, Aqua, and Eraqus were oppressing him?
When Ventus asked why he was never allowed to leave home, they said that it's because they were just looking out for him, even though they knew he could handle himself quite well. But alas, there was something that they were not telling him. It was for his own good, but they also hid something from him. He ended up finding out the truth from Xehanort: the real reason why he was never allowed to leave home was because of the creation of the X-Blade. The X-Blade is created when a heart of pure light and a heart of pure darkness intersect, with both being equal in power, and can only be created if those two hearts fight. Vanitas spread the Unversed across the universe for Ventus to fight and get stronger, so that he can absorb his power and wield the X-Blade. Ventus was very concerned about Terra falling under the posession of darkness, not knowning that he, too, would also fall under the possession of darkness, by being forced to fuse with Vanitas.
With all that said, is it possible that Ventus may have figured out that Terra and Aqua were oppressing him by not telling him the truth? I have a strong feeling that the reason why they withheld the truth from him was to protect his feelings; had they told him the real truth, he might have gotten the impression that they were purposely trying to keep him weak, and if he got that impression, he might turn on them. Thus, they decided that the best thing to do was to not tell him the whole truth, and hope that he doesn't figure out that they are oppressing him. Of course, could it still be possible that Ventus figured out that they were oppressing him before he found out the real truth from Xehanort?
