My biggest issue is Steven and Connie's relationship
No! I think Connie is a right girl for Steven but my problem with this relationship is Steven will outlive Connie because his half-immortal status. Look at Greg and Rose's relationship! I know Rose give up her physical form to give birth to Steven but i think she did this because she know Greg was going to die and she doesn't want to see him DIE!
Crewniverse are NOT aware of this issue? Steven would absolutely be DEVASTATED with Connie's death! Steven will NO longer being the happy kid anymore!
How would Steven deal with this HUGE issue with him outlive Connie?
