SPOIIIILEEEEERS!
So! After Steven reunied with his gem, (in change your mind, of course) we never actually saw the gemstone again. This brings a few questsion:
The gemstone is IN Steven again? If yes, still on his navel? If no, and he is fine, does he got his powers? Etc. You can think out the other questsions.
What do you think? ✌️
